Help Please! A few months ago my husband and I began trying to conceive. My cycle were always pretty normal before about 28-32 days. Now all of a sudden since we have been having unprotected sex they have completely flipped. They are only 20 days apart and not normal. Before I would start heavy and go light, now I spot for two days have one semi-full day and spot one more. This is not normal for me. Could this have something to do with having unprotected sex?
