Hi,

I am 29. I have always had irregular periods. I conceived after taking ovulation pills (that was 4 years back). I had copper t for a year but had to remove it since it had come down to the Fallopian tube. Removed it in March 2013. A transvaginal scan reported I have PCOD and glycomet 500 (metformin and hydrochloride) (Metformin - Wikipedia, the free encyclopedia) twice a day was prescribed since I am 8kgs overweight.
My LMP was 29th March. Had sex severral times, but unprotected sex once between 10th April - 14th April. Didn't get my periods yet. Have nausea, get crapms, frequent urination, find it hard to sleep at night, feel dizzy and very weak.
Took a HPT on 3rd May, but it was negative.
Should I take another test? When? Can I be pregnant with PCOD and irregular periods??
