I have had a slightly odd cycle this month, I had hardly any period last month, literally just one day of a tiny amount of spotting. Today I started spotting which fits in roughly timing wise (I think I ovulated a couple of weeks ago - I had all the usual signs) but rather than my period starting I've spent all day with the most terrible period pain, to the extent at one point today I even considered calling an ambulance I was in so much pain. Even my miscarriages weren't this painful.
It's easing a tiny bit because I'm in bed with a hot water bottle and have taken some co-codamol, but what on earth could be going on? Am I getting a monster period because last month's didn't happen? I'm 42 and definitely not pregnant.
