I have irregular periods bcz of thyroid though I take medication it is still irregular and ranges from 40-50days between periods. I took opks and got my peak on cd35 and got my periods on cd49. I took pregnancy test on cd48 and it was negative. I had normal periods for 7 days and then took pregnancy test on CD12 because of few symptoms and a unusual peak on opk and got positive pregnancy test. Is this normal??? I have my doctor appointment only after 10 days. Please help!! TIA
