Could this all be signs of pregnancy?

I’m probably overthinking, but let me know if I’m not.

Today is May 31st, and the last time I had sex was the 27 and 28th, pull out. Then before that, the 22nd. (Aware of consequences btw)

On the 29th I got super sharp pains in my vagina area that lasted about 10 seconds and haven’t had that since. Today at the mall I felt nauseous, which I haven’t felt before. I ended up getting a drink but was not hungry despite not eating yet, and it was 2:30 PM so I felt like that was unusual. I’d say that not eating was the cause but I didn’t feel hungry or a need to eat at the time. (I still haven’t ate and it’s hours later)

Then tonight I got some cramps, pretty sharp ones too and I don’t get those unless I’m on my period or maybe a day before, but I’m not near my period for a while.

Any thoughts on what this could be?
