I had my LMP on 11 November, and have a 33 days cycle. Although I didn't have unprotected sex, I am worried about pregnancy. I was diagnosed with pcod in august but after changing my food and lifestyle habits I had regular periods for 3 months. Now this month again I was supposed to get my periods on 14 DEC but still no sign. As I do fast dance exercise like zumba and aerobics at gym I was still concerned and got beta hcg on 19 dec which was negative. It showed <.100 hcg. Now should I wait longer for my periods to come or see a gone for medication. I was hoping that I would control pcod without medication.
