Okay so I had sex for the first time on the 8th of this month (July) and today I feel sick like nauseated and I feel hot. I took a pregnancy test and it can back negative because I had unprotected sex but he pulled out in time and then I had protected sex again after.

Is it just cuz it’s my first time and my body isn’t use to it? And it’s 27 degrees where I am right now so could that also be a reason? Also I’m on the depo shot
