Orgasm Headache??

Amps

OMG, so Sunday I was SUPER aroused and I was on my second day of my period (tmi) and it was heavy. So that's when we took the party to the shower. Everything was fine and dandy until I came to my climax. OMG, I felt as though my head was being crushed by something. This headache nearly brought me to tears and I am certain in the mithst of it all I blacked out as well. I had never experienced this before and I was scared. A little back story that I think maybe relatable to this incident...My period was 10 days late and I had symptoms of a flu but didn't really get sick. Then my period made an appearance and it's not normal it's light. Also since the climax headache I've been having minor headpain. Ok, let's bring it back to the present day. I attempted once again to have sex and reach my climax and as I was coming close, I felt the pain again. WTF is going on!? so I stopped and now I'm wondering if I will ever be able to enjoy sex again? HELP ME lol Has anyone gone through this? does it ever go away or is it a sign of something more serious?
