I stopped wearing my ring at about 4/5 months, it was just getting uncomfortable...everything with this pregnancy is that way, having twins is way harder than I thought! I for some reason never hit the nesting stage, so my house is a crazy mess, and its even worse now that I am on STRICT Modified bed rest. I can only be on my feet if I have to,(bathroom, water refill, or something small with my 3 year old) I am 33 weeks and 4 days and having contractions every 2/3 minutes but they let me go home with the promise of bed rest since I have not dialated any yet...I really need to make it to next friday(35weeks)
As for the nursing bras and tanks, everyone is sooo different, I bf my son and I didnt have to buy anything bigger then what I wore for my pregnancy, this time my left boob has grown about 3 sizes and the right one maybe 1 cup size, so I have just been wearing my normal nursing ones from last time. Also I recommend getting some without the underwires, since they told me that will dry up your milk if they are to tight....
