feeling dizzy and nauseous after sex /u/Ardeth_rue Sex

I (F19) have recently started having PIV sex with my boyfriend (M19), both of us virgins in the penetration sense. The first time we had sex I did bleed a little, this was only visible on the condom, and never in my underwear/on any tissue, but I felt very dizzy and nauseous (I felt as if I was about to throw up) immediately after. I didn’t feel sick at all during the act, I was actually enjoying myself, this only happened after. We’ve had sex around three times since then and each time after I have been feeling really dizzy and light-headed, and I get a headache. I am not quite sure the cause of this, and is this normal? is there a way we can fix this? I feel like we have pretty standard sex… but maybe we are doing something wrong?
