My periods have been a little erratic the last few months, not massively but slightly, and EXTREMELY painful, but only on one side and only for a couple of hours the first day! I have had a scan/bloods etc and all appears normal. Going on the latest my period has been the last few months, I am now 3 days late, have had cramps for the last 5 days but no where near as painful as normal, had very slight spotting earlier today, but nothing since. Did a pregnancy test yesterday, was negative. Have been TTC since June and it's driving me crazy, just want my periods to be normal and regular. Any ideas what's going on?
