Hello, I am 31 years old and have irregular periods. My gyne checked my thryroid levels and progesterone and estrogen levels in March, she everything everything was normal and I was ovulating. My periods range from: 29, 32, 38, & 42 days. I had my copper IUD removed 19 days ago. I am 37 days past my last menstration. I took an ovulation predictor kit and got the peak symbol on cycle day 18. I was expecting either my period or a positive pregnancy test by now. any thought?
