i feel very ill lately

so ever since i had unprotected sex with my boyfriend , i feel very nauseous lately and my anxiety is acting up... I had sex thursday and saturday (yesterday) i read that you know when ur body is telling you something cuz you never felt it before . and i actually feel it in my heart that i am even though it’s still early to tell , my anxiety never been this weird before and i never been nausous either .. but my period isnt til the 25 th so i have a long ways to wait and rest 😷😭😭
