Could I be pregnant??

So me and my bf did it without protection on February 21, the day after my period ended... I didn’t feel him do anything inside and he’s 99.9% sure he didn’t do anything either..... but it’s now april 3 and 3:21am..... I can’t sleep, i have a migraine, stomach pain, dizzy/light headed, and was sweating but now I’m cold. And I’m supposed to get my period in 5 days. Are these signs of pregnancy?!?
