I have polycystic ovary's... I have not had a regualer period since Nov.2009.. however, last month I thought that I was starting to have one and I bled all that week off and on.. not heavy like I usually do it was pinkish ..for the last 2 or 3 weeks I have been having cramping in my lower abdomanl and bloating to the point I can't fit in my jeans.. also, I have had tender swollen breast and headaches.. I did all of this with my only son 6 years ago ... Is it possible that I am pregnant?
