Hi, DH and I have been TTC for a few months now. My af is usually fairly regular but this month it arrived 10 days late, and when it did arrive it only lasted for 1 day and I only needed to use 1 tampon, (normally it lasts 3 days). For a couple of days after that I had barely-there-evidence of blood when wiping after peeing- sorry TMI! It's now 6 days after the "period" arrived and my nipples are still very tender which is unusual for me. I just did a clear blue test and it came back negative. Would anyone be able to tell me what is going on!?
