Omg has this happened to anyone?

I'm 8 dpo today. 34 yrs old and TTC baby #1.
Last night I got a crazy cramp when I got off the couch!! It felt like someone stabbed me and doubled me over!! Then I was fine... About 2 hrs later my head was pounding, I was dripping sweat, nauseated and dizzy...... Now, I have had migraines for years, and it was nothing like those. I've never felt anything like it before ever!!! By 3am I was perfectly fine again.... Thoughts??
