Things You Can Do In First Trimester But Not In Second

The first trimester of pregnancy is filled with excitement, anticipation, and a bit of anxiety. It is also when women face some worst pregnancy symptoms. With things such as morning sickness, fatigue, or even pregnancy insomnia, it is no wonder that those expecting are excited to transition out of the first trimester and into the second. What many do not realize though is that entering the second trimester means far greater restrictions were experienced with the first. Therefore, even though women may be feeling better and have energy, many of the things they could do in their first trimester they cannot do in the second. Leaving women to figure out what a new normal is as they navigate the journey of pregnancy.


As women enter their second trimester of pregnancy, they have more restrictions due to the rapid development of their babies. This means that everything that women consume, their activities, and the amount of sleep they have all have a direct impact on babies. Because of this, even though women may feel like they can conquer the world with their newfound energy, they need to ensure that everything they do is safe and healthy for both themselves and their unborn babies.

Here are things you can still do in your first trimester but not your second.

BABYGAGA VIDEO OF THE DAY

10 High-Impact Sports

Overall, if doctors had their say, they would restrict women from doing any high-impact sports throughout pregnancy. But because women will not always adhere to these recommendations, there are better times during pregnancy to take risks. And that time, according to Healthline is the first trimester.

The first trimester is the safest time for pregnant women to do sports where there is a risk of falling. This is because, per the publication, the baby is “extremely protected” inside the uterus. As such, if falls occur, then there is less risk of complication.

This means, however, as the baby bump begins to show that high-impact sports are off-limits during the second trimester. And because of this, things like skiing, ice skating, skateboarding, or any other sport where there is a high chance of falling, are off-limits after the first trimester.

9 Lifting Heavier Items

If women have been lifting weights or heavier objects before becoming pregnant, they likely do not have to make much of a modification during the first trimesteraccording to BabyCenter. But, as the baby bump grows and the center of gravity shifts, Doctors will recommend that the amount of weight being lifted decreased to a more manageable weight during the second trimester.

Further still, per the publication, the ligaments begin to loosen during the second trimester. If women lift too much and/or twist in a way where the ligaments are overstretched, pregnant women can hurt themselves. This is why lifting heavier weight is allowed for those who previously lifted during the first trimester and not for those in the second.

8 Sleeping On Stomach

During the first trimester of pregnancy, it is fine for women to sleep on their stomachs if it is comfortable for them, according to The Ohio State University. But, as they enter into their second trimester, sleeping on the side is the preferred position for sleep. And this is why it is not recommended after the fourth month of pregnancy.

The reason that women should not sleep on their stomachs as they make their way through the second trimester of pregnancy is that sleeping on the stomach can proper circulation of blood from mothers prevents to their babies, per the publication. As such, women can feel nauseous or lightheaded and babies will receive less oxygenated blood. All things that can cause complications in the pregnancy.

7 Laying On Back For Long Stretches

Much like laying on the back during working out, laying on the back to relax is fine to do during the first trimester but not during the second. This again has to do with decreased circulation through the body.

If women want to lay in a semi-prone position, that is safe to do. This is why so many women find it more comfortable to sleep in a recliner on some nights so that a position other than sleeping on the side can be done. As long as they are not completely prone, sleeping or lying like this from time to time, according to WebMD.

6 Wear High Heels

The first trimester is a time when most women put on very little, if any weight. As such, they can continue to wear high heels with no problem, should they choose to do so.

According to Gotham Footcare, when women enter their second trimester, they begin to put on a majority of their weight. This is because it takes more calories to help babies develop.

With this weight gain, the feet can begin to expand. The larger feet in conjunction with the weight gain put “pressure into the joints and muscles of the feet.” As a result, women will likely be uncomfortable shortly after putting the shoes on but, per the publication, the pressure can change the structure of the foot permanently. This is why high heels are not recommended after the first trimester of pregnancy.

5 Working Out On Your Back

While it may feel comfortable to do exercises laying down to get some relief from the new forward weight of the baby bump, exercising on the back cannot be carried over from the first trimester to the second.

According to What To Expectafter the fourth month of pregnancy, the uterus can press on blood vessels and cause a decrease in the blood flow through the body. This can cause symptoms of ill health for those expecting and be unhealthy for unborn babies given that a lack of circulation for long periods can cause pregnancy complications.

4 Sit For Longer Than 30 Minutes

Women working in jobs that require them to sit for long periods likely will not have any problems during the first trimester of pregnancy continuing to do so. But, during the second trimester of pregnancy, it is recommended that women do not sit longer than 30 minutes at a time. This is so that they do not increase their risk for blood clots, according to FamilyEducation.

However, given the amount of water that women are drinking and the growing uterus pressing on the bladder, women will likely get up every 30 minutes or so to head to the restroom.

3 Spending Time In The Sun

Spending time in the sun during the first trimester is no different from spending time in the sun pre-pregnancy. Sunscreen and safe sun practices are necessary, but a bit of sun exposure is healthy for women in this stage of pregnancy.

According to LiveWellas the volume of blood increases in women’s bodies, they raise their internal temperature. This means they are at a higher risk of heat stroke. As such, during the second trimester when women are getting larger ad their body temperature rises, they need to take care to stay out of the direct sun during peak hours to ensure both they and their unborn babies remain safe.

As women enter the second trimester, their skin becomes more sensitive as well. And because of this, they are more apt to burn. Again, making sunbathing an activity that is okay during the first trimester but should be avoided during peak hours during the second trimester.

2 Dental Procedures

Seeing a dentist during pregnancy is important to help keep healthy teeth and gums, according to the ADA. But, if there are elective procedures, they should be done during the first trimester or after delivery.

If there are emergency procedures that need to be done during pregnancy, per the publication, there are ways to safely ensure that procedures can be done without bringing harm to mothers-to-be or their babies at any stage of pregnancy. It is the procedures that do not impact health that should not be done after the first trimester to keep those expecting and the babies as safe as possible.

1 Spicy Food

There is nothing wrong with eating spicy food when pregnant. However, there is a very real difference between eating spicy food in the first trimester versus the second. And that is why those expecting can eat spicy food at the beginning of their pregnancies but may have to give it up during the second trimester.

According to OnlyMyHealththe risk of acid reflux is greatly increased during the second trimester when women choose to eat spicy food. Something they may not have experienced at all during the first trimester. As such, eating spicy food sparingly or not at all after the third month of pregnancy is recommended for those women who are prone to indigestion, heartburn, or acid reflux after eating spicy dishes.
