Sorry I have no experience of ovarian cysts burst or not. If your periods have been regular though, then surely it's your period? You should have had normal warning signs? However I think you will need to consult a doctor on this one if you are concerned and if the pain is that bad, bleeding aside - you should not wait 6 weeks for a rescan
- unless you think it's normal period pain? . I hope you decided to take some action if necessary today.
Do let us know and hope the pain eases soon?

edit - sorry have just read your last period was very late so in that case I would defo consult a doc unless you are sure it was a period - just to be sure
