I fainted 7 times just during the Lent season. Im 30 Weeks. The last time I was in the shower and before you know it I woke up to cold water and my dog howling and whining. I mainly fainted because my sugar was low. I gave up sweets and junk food during Lent and it took its toll on me
I fainted once at 16 weeks! Everything was ok though :)
I haven't ever fainted although I came close a few times! My ob did say it was possible. I would let your dr know tomorrow just to be safe though.
