I have irregular period. Glow said I would be at my peak ovulation on the 7th but my ovulation test wasn't positive. so I had my sperm donor come over I also had him come over the 8th which t said I was ovulating. I have unprotected each time. But what are my chances. I take prenatal vitamins every day. I just am getting nervous. I so badly want to be pregnant. But being irregular it's extremely difficult.
