You鈥檝e made it through two trimesters of pregnancy. That pesky morning sickness magically disappeared, you鈥檝e gotten used to that weird elastic band at the top of your jeans, and your besties are planning the baby shower to end all baby showers. Congrats! Now you鈥檙e on the home stretch. Your bump is really, truly bulging now, and you鈥檙e starting to notice鈥 changes. If you鈥檙e kind of wondering what鈥檚 going on, check out what you should (but might not) expect from your third trimester.

1. Raging Heartburn: Okay, so this isn鈥檛 the only part of your pregnancy that comes with some heated heartburn. The influx of hormones caused the not-so-nice post-meal sensation earlier on. It鈥檚 entirely possible that you鈥檝e had heartburn for the duration of your pregnancy. It鈥檚 also possible that it hasn鈥檛 touched you 鈥 until right now. Your growing baby is starting to run out of space. As she presses against your stomach, you may start experiencing trouble with your digestion. This can include heartburn that鈥檚 much more noticeable than before.

2. Considerable Constipation: This is yet another joy (said with total sarcasm, of course) that comes with your third trimester-sized baby. Now that she鈥檚 fully pressing on most of your digestive tract, whatever is moving through you is suddenly slowing down. Your preggo hormones aren鈥檛 helping the matter either. So don鈥檛 be surprised if your normal morning bathroom routine just isn鈥檛 happening. Keeping yourself hydrated, eating plenty of fiber-rich foods (just don鈥檛 overdo it, as that can have the opposite effect), and getting physical activity can all help your slowing situation.

3. Discharge: Yeah, we know 鈥 yuck. Suddenly you鈥檙e on an all panty liner all the time routine, and you鈥檙e not sure why. As your hormone levels change and your body begins prepping for the end of pregnancy, you may notice more discharge than what you usually experience. Typically, this discharge is clear or whitish. If it鈥檚 chunky (again, yuck), is bloody, has an odd odor, or in any way troubles you, call your doc right away.

4. Fatigue to Fight: Ugh! You thought the massive case of pregnancy tireds that you had was gone and done with after your first trimester. You had a spring in your step and plenty of energy during trimester two. Now that you鈥檙e in the final phase, that fatigue is creeping back in. Between all of that extra weight you鈥檙e carrying around (we鈥檙e talking the baby, not your butt) and the way that those stress-dreams keep waking you up all night long, it鈥檚 no wonder that you can barely make it through a day of work without needing a nap.

5. Shortness of Breath: Your baby isn鈥檛 just wreaking havoc on your digestive tract. She鈥檚 pushing all of your internal organs out of her way. The bigger your uterus gets, the less room there is in there for your lungs to expand. Some shortness of breath is completely normal during the end of your third trimester. But if it鈥檚 getting in the way of your daily activity, you have pain in your chest, or you notice a sudden inability to catch your breath, get to a doctor immediately.

6. Veins That You Can See: Spider and varicose veins are completely common in the third trimester of pregnancy. Your blood volume is on an upswing, majorly. Couple this with the pressure your baby is putting on the blood supply around your uterus (making the blood return to your heart slow slightly), and you鈥檝e got a recipe for enlarged veins. Don鈥檛 stress: It鈥檚 likely that these not-so-pretty lines on your legs will fade after pregnancy.
