We had sex, he was wearing a condom,when he came he let his penis inside me for few moments as he was tired and laying on me then he take it out, as his penis is now loose, the condom was covering the first part of it( the tip)is there any chance that he put semen inside me? Am terrified of getting pregnant or Stis?I’ll have my period in 7 days( hopefully), I dont take contraceptives .
