Having cramping feelings after first and second time sex... but my period isn't supposed to start for another week or 2... how concerned should I be? I thought you didn't feel pregnant symptoms until around 2 weeks after but it's only been a few hours since I had sex. Is this normal for after first sex to have a kinda achy feeling? I haven't felt nauseous at all, just cramps. PLEASE HELP IM SCARED AGGGG
