Is there a possibility ?

My boyfriend and I have been having unprotected sex with no type of birth control (he doesn't pull out either 🙄). Anyways we had sex on my birthday (7/22) and that was the day I was most fertile...then my period came veryyyyy early like 5 days later and it wasn't due until the 13th of This month (August) it lasted about 3 days and was very light and this time around I'm feeling very lightheaded, nauseous and anxious and I've been sleeping a lot...I don't know if it's too early for a pregnancy test or what. But have you guys had any experiences like this?
