I feel silly even asking this, but I thought you 3rd tri ladies might have some insight.
At 21 weeks, I do think my belly is pretty big. I have some lower back pain and I'm starting to feel like my abdomen is heavy and uncomfortable by the end of the day. Really though, it's not that bad.
My funny but caring husband, who is not only a man (who wants to "fix" everything!) but also a nurse, keeps bugging me to get one of those support belt things.
In case anyone doesn't know what I mean: http://www.amazon.com/s/ref=nb_sb_sabc?url=search-alias%3Daps&pageMinusResults=1&suo=1355793435603#/ref=nb_sb_noss_1?url=search-alias%3Daps&field-keywords=maternity%20support%20belt&sprefix=maternity+suppo%2Caps&rh=i%3Aaps%2Ck%3Amaternity%20support%20belt
Does anyone actually wear these things?! Do they work? Where do you actually buy one? Can you try it on first? Can you see them under your clothes? I am baffled by the whole concept.
