Hi, everyone just wanted some opinions and experienced comments please. :) I am a 20yr old mother of one. Reg. perods are 30-35 days. My last period was Oct. 22nd 2008. I last had sex on 11/2/2008, on 11/15/2008 I experienced some light spotting and . that's it. Of course when I missed AF the next week I thought pregnancy so I took a test that was negative. I also missed the one for Dec. Fast forward to today 1/25/2009 and my AF was due 3 days ago and hasn't came yet. So that's 3 months no period I have taken 5 pregnancy tests all urine and ALL negative. The last test was at the E.R. on 1/9/09 because I was having some pelvic cramping and that urine test was negative. I have been experiencing some symptoms but I doubt they are related to pregnancy since 5 tests are negative so I'm thinking PCOS. Symptoms are: Sore breasts, weight gain ( 10 pds since Nov.) headaches, constant pelvic cramping, little throbbing "pulsations" (I guess that's what u call it) in the pelvic area also. Um, the doctor's won't do a blood test to check for anything else, I am not on birth control and never have been, not under a lot of stress although I do have a 4yr old son.
