Thanks. I'm so confused because I wasn't supposed to be O'ing right now. I was supposed to O around the 13th, then had spotting for 6 days. Bought the OPK's but wasn't going to use them as I was waiting for AF to show. Have all signs of AF for 6 days, cramping, backache. But I've also been nauseous which is not normal for me. I've taken HPT's and seen a very very very light line but it hasn't got darker over the last 2 days. So I don't know what is going on.
