I am a 39 year old woman. I have had 4 healthy
children, the youngest is almost 9 years old. The only form of birth control my husband and I use is condoms, no drugs, no shots, no pills...I have periods every month. Right now I am 2 weeks late with my period, but have taken 3 pregnancy tests...all negative. I am nauseous, have heartburn, tired, food aversions, hair loss, and huge boobs! What's going on?? I did take Excedrin before I realized my cycle was late...any ideas??
