I had my period last month for 2 days first day was spotting an brownish an the second it was a full day but brown , my period was the 20th. An I ovolated on the 30th -through the 3rd. My husband an I have been trying to conceive for months, I have irreguler periods I lost 40 pounds an my periods are reguler now , I've had a reguler period for 5 months now until last month it only lasted 2 days an brown. My breast seem fuller but just my nipples are sore.my right seems more sore then the left I had a pregnant test it was negative, but I think its to early to tell. I've been having some cramps at the lower of my stomach like a period cramp but its not time yet. The nipple soreness has been going on little over 1 week. Could this mean pregnant or do I need to get checked for breast cacer? I'm worried cause cancer does run in the family. I had a misscarriage 4 yrs ago an I don't have any children so I'm not sure what's going on.. I know you can't tell by talking to me but it would help me a little bit to kind of have a idea.
