Could this be early symptoms?????

So I had unprotected sex three days ago. He didn’t cum inside me but there was drop in my pubic area before I finished myself off. I didn’t think it mattered because it wasn’t really close to my vaginal opening, but I did rub my clitoris.

Yesterday I felt really bloated and today I’m having cramps and yawning a lot. I’m on nexplanon and my periods are already irregular because of it.

Could I be experiencing early pregnancy symptoms??
