Im 15, and think im pregnant but i got a big question please, !?

im 15 andd me and my bf had sex and i was on top and he cummed inside me.

i am haveing hot flashes eating alot and my nipples are sore. and im like 3 or 4 days late.

and its been like 7 days now.

so theres a big chance in it.

but my question is. i have a cyst on my left ovary and it always hurt when i got my period or something.

but theres a big chance im pregnant so even if im pregnant.

will it still keep hurting like i feel before i start my period?

and will it hurt the baby?
