Hi Charm,
I can't help too much but I do know I have had random months where I have had very sharp pains around o time. Before my first m/c I used to always know when I was o but now I don't get the symptoms I used to, only some months but I know I o every month.
Are you still in pain now? I would definitely call the Dr or hospital for their advice if the pain persists for a continued amount of time. Mine only usually lasts a couple of hours. The hospital will soon tell you whether to go in or not.
Hope you are feeling better soon and can make it to Friday night chat
