At 28 weeks pregnant, symptoms include Braxton Hicks contractions, varicose veins and spider veins, constipation, hemorrhoids, weight gain, back and body aches, and heartburn. You should still be feeling your babies move, although it may feel a bit different, since they have less space now. Here are some of the other symptoms you can expect:
In the third trimester, you might be feeling some Braxton Hicks contractions, also known as false labor. Braxton Hicks feel like contractions but are irregular and don't actually mean you're in labor. They might feel like cramps or a tightening sensation in your uterus. If you feel contractions, take a break and rest, put your feet up, or take a bath and stay hydrated if you can. If they slow down or stop, it's very likely Braxton Hicks. You're more likely to feel Braxton Hicks when active, dehydrated, or when it's hot.
You may have tiny red veins at the top of your skin – called spider veins, or spider angiomas – on your face, neck, and arms. This is caused by hormones like estrogen, and the redness will probably fade after you deliver your babies.
You could get varicose veins, or veins that become swollen and blue, on your legs. This is caused by decreased blood flow to your legs because of the weight of your uterus. Varicose veins typically improve after delivery. You can prevent the intensity of varicose veins by getting up and moving around if you sit or stand in one place for a long time, not sitting with your legs crossed for too long and putting your feet up when you can. Exercise, elevating your legs, avoiding tight clothes, and wearing support hose can all help with the discomfort.
Hemorrhoids are swollen blood vessels on the rectum and anus that can be painful and uncomfortable. They can be caused by constipation and straining to have a bowel movement, or simply by the weight of the uterus on your pelvis. Trying your best to prevent constipation, but doing things like eating high fiber foods, drinking plenty of water, walking, and exercising – can prevent hemorrhoids or at least prevent them from getting worse. If you do have hemorrhoids, you can talk to your doctor to learn other ways to get relief.
You should be able to continue feeling your babies move, although their movement might not feel as strong since they don't have as much room as they did before. Your provider may suggest keeping a daily count of how often your babies move and advise you to call them if you haven't felt movement in two hours or so.
In the third trimester of pregnancy, you may be gaining over one pound a week. The general recommendation is to gain anywhere between 35-54 pounds total during a twin pregnancy, but this recommendation varies based on your pre-pregnancy weight. Your provider can help walk you through healthy habits and suggestions for achieving healthy weight gain for your pregnancy specifically and may refer you to a dietician.
Maintaining a healthy diet is important so that you get all the nutrients you need to help with healthy weight gain and your babies' growth and development.
You will most likely feel back pain and body aches once you hit the third trimester of pregnancy (if you haven't experienced it already!). This is because of your growing belly and the strain it puts on your back, and the fact that your spine is likely curved with your growing belly. Back and joint pain can also be due to rising levels of progesterone that continues until delivery, which can also loosen up your joints.
Heartburn is caused by slowed digestion and a relaxed esophageal sphincter due to an increase in progesterone. As your uterus expands in the third trimester, it may push against your stomach and make heartburn worse.
