Personal but I had sex 2 nights ago trying to get pregnant I have a sharp cramp right now can that mean anything?

No

no

The cramp might be from ovulation. Or not. But it's far too soon for it to have anything to do with pregnancy.

No. Way too early for that. If you are old enough to have sex you are old enough to educate yourself on the female reproductive system & pregnancy. This is something you should have learned in school in grades 6 & up.
