Sex headaches!!

Joanna
Anyone else have experienced bad headaches like migraine type headaches right after sex?? 
My hubbie and I had sex a few days ago and when we both finished I just got an intense headache, I think it was a migraine actually. I had to sleep it off. I'm 35 weeks pregnant and it's never happened before. I was kinda freaking out about the pain since it was the first time it's ever happened.
