i’m only 16 and had sex for the first time yesterday and it wasn’t exactly planned so he didn’t have condom but he pulled out and came in his hand but i’m just really paranoid bc of pre cum even though it’s a very small chance that I could get pregnant from it. should I buy some kind of expensive pill or just wait until my period is supposed to start in 6 days? and if it doesn’t start i’ll take pregnancy tests. please someone help!
