Im 25. i  was diagnosed with pcos about 2 yrs ago but always had regular cycles. in Jan 2013 i had a regular cycle but then Feb 2013 my cycle was 3 days late and only lasted for 3 days. Ive been trying to get pregnant. lately Ive been having headaches and backaches, tired more than i usually am, and Im never full. also sometimes i still have feeling of light cramps. i had my ovaries checked, no cysts or nothing abnormal   can someone help? i was going to wait to see what happens for march 2013 to take the hpt.
