I had a contraceptive failure within 12 hours of my ovulation window ending (roughly, it's hard to be exact as I wasn't tracking). I took the MAP the morning after but I since realised that my ovulation had finished so it would probably be redundant. Period is 3 days late, had a negative test two days ago No sign of AF yet, I have twinges below my belly button, not pain but twinging, unlike usual cramps. I have no idea what this means, has anyone else ever had it? Any advice would be appreciated, I don't know what to do at this point if test was negative but AF isn't making an appearance.
