Don’t feel right..(tmi)

I’m 18w4d. I had an orgasm a few hours ago and now I feel really strange. Short on breath, lightheaded/dizzy and when I just went to the bathroom part of my mucus plug came out (I know it reforms). It was a decent amount, clearish and like egg whites.

It kinda feels like dehydration but I’ve been keeping fluids in me all day.

I feel like I’m gonna pass out if I stand up.

I am not on any restrictions from my doctor as far as sex/masturbation.

Anyone else??
