What do you ladies know about hormonal fluctuations? 20w2d and I am so dang tired, weepy, my breasts hurt more than they have in awhile, and my feet and hands are swelling. A lot of those symptoms were very minor for the last month or so, now it's full force. These symptoms seem WORSE than my 1st trimester symptoms!
