What are y'alls experience?

I know this sounds crazy but I'm either having random odd body pain or I'm having really early pregnancy symptoms?!?!

Today is my day after my highest ovulation day. My SO and I had intercourse multiple sessions and we also had intercourse a few times during my ovulation week. I woke up at 3am this morning with the worst nausea/stomach pain. Went back to sleep and woke up again at 8am nauseated still. Thank god I didn't need to work this morning!!! I waited a couple hours before I had breakfast and I honestly felt like I was going to vomit what I just ate.

I've read it all and I know it's super unlikely to have symptoms the first week of pregnancy but has ANYONE else experienced this before?????
