Pregnancy

Just need some answers no hate! I had sex about a week ish before my period and my significant other nutted in me.I got my period 2 days late but I did get it. Then after my period was over. About a week later I have started having cramps with is unusual when my period is done, headaches, stomach feeling weird (kinda nauseous), emotional and I threw up a little. Is there any way I could be pregnant?
