Ive fallen

I reasantly had an episode. I haven had one in years last time was like when i was 21. Out of no where i fainted. I was tending to my daughter tgat had a cut on her toe. And bam there i go. This has happened before in my life and this would be tge 4th time over the yesrs. The first time i was 16, the 2nd time i was 18, 3red was 21 and know at 31. Iv had a tubal litigation at 27 so its been 4 years sens than and ive gone to my doctor and he keeps telling me that there is no way i could be pregnant, cuse of the tubal. So i wss wondering if anyone alse has had this issue. Or has any advice.
