Your presentation is quite unique and rare I must say. We cannot really predict the exact cause and possible long-term effects without thorough evaluation. For this I would advice a CT scan
of the brain to check on blood circulation and a transvaginal ultrasound
scan of your reproductive system. Checking on your coagulation profile would also be a wise step.
Only once you are thoroughly and most elaborately evaluated will we be able to comment on the exact cause, possible relapse and long-term effects of the same.
Hope this helps.
