Hi, im a 32 yr old female who last year had a baby in may 2010. October 2010 I started my cycles again ranging from 32 - 34 day cycles. January 21, 2011 was the last time I had my period. I have done many Pregnacy tests, including an ultrasound on March 7 showing no cysts , nothing wrong at all. A doctor gave me a shot of progestone. I did experiece cramps but still didnt get my period. I havent been under any extra stress, and my weight is steady. The only thing that i can think that has changed is I ve been taking OTC PM pain relievers to relieve my pain from a cap on my tooth since the middle of Feburary. The pain is getting better, so i ll be stopping soon with the PM pain relievers. My question is can the OTC PM pain relievers be interfering with my cycle? I dont have health insurance, so going to doctors isnt feisable. Thank You from Out of wack Mom
