Hey girly, I am going through the same thing right now actually. The exact same things are happening with me, So Im on the same page. My nipples hurt too, and my period is soo irregular that I dont know when Im supposed to start or miss it. :/ Im so confused. And I know for a fact that theres a chance that I could be pregnant cuz my boyfriend and I werent careful and had an accident. I havent really even had an appetite lately, just like nothing sounds good to me anymore, and yes I have gained weight. Gahh, this is soooo frustrating to me, I just wanna know. I need to buy a pregnancy test again and take it or go to the doctor ferrr sherrrr.
