Hi, I was diagnosed with pcos a few years ago, but not taking any sort of medication. My husband and I have been ttc for the last few months and I haven't had my cycle since 12/25. That said, I've always had an irregular cycle, but this one seems to be lengthier than usual. I've taken a couple of hpt's but they each show negative results. Are there any other reasons why my mc could be so late?
