The biggest hurdle my husband and I had in conceiving were my irregular periods. I had no earthly clue when I was ovulating. We have been off bc since June and seriously trying since September. I had to throw ovulation tests out the window when I found out that because of my PCOS I had an almost constant LH Surge so they would be positive for ovulating a lot of the time. And then I also tried going by when I had the most egg white like cm. But every cycle, I would hit that wrong too. The funny thing is, we got pregnant when we did it and I didn't think I was ovulating even. It was just spontaneous and we made something beautiful from that night! Totally boggles mind how it all happened but so thankful.
