The third trimester begins in week 27 of pregnancy and lasts until you give birth, which may be around week 40 of pregnancy. In other words, your third trimester lasts from month 7 through month 9 of pregnancy. At your first prenatal visit, your health care provider will help you determine an expected delivery date (EDD). Your EDD is 40 weeks from the first day of your last menstrual period (LMP). It’s important to remember that your due date is only an estimate — most babies are born between 38 and 42 weeks from the first day of their mom’s LMP and only a small percentage of women actually deliver on their due date.
Here is your guide of what you might experience in your last and final trimester.

WEEK 27-29:

Welcome to trimester 3. Pretty exciting! Just 3 months to go for your little joy to arrive. Well, this is still going to be accompanied by a few symptoms. You may experience swelling or edema in lower extremities and hands due to fluid build-up in the body. To spell off, avoid standing or sitting for long hours. It might get uneasy when you feel heat rashes due to over-heated body, increased perspiration, and the friction caused by skin rubbing. Relax and let your body cool. Moisturise well.

WEEK 30-32:

In week 30, all you experienced in the first trimester is going to get back, tender breasts, heartburn, etc. All this is happening because pregnancy hormones are now relaxing your muscles and preparing you for the delivery.
Up in week 31, your enlarged uterus has now squished all your internal organs leading to shortness of breath and giving you a feeling of discomfort. All this is going to go away in later stages, as your baby moves down to pelvis in preparation for delivery.
Now in week 32, your body starts warming up for birth. You might experience your uterus tightening or hardening regularly, technically called as ‘BRAXTON HICKS CONTRACTIONS’ or FLASE LABOR.
