intense headache before orgasm

so my boyfriend was eating me out and he was going hard lol. it felt amazing and i was about to orgasm but i got this extremely severe pain in the left side of my head at the base of my skull and i had to make him stop because i literally felt like i was going to pass out. i looked it up and google said it's normal to have a headache before orgasm but is it normal for it to be that severe? it was like a stabbing pain and it lasted through the night. any thoughts?
