I had unprotected sex with my boyfriend three days after my period.He used the withdrawal method but not soo sure if he ejaculated some in me.I took postinor 2 four days after.But i took all the pills at once.Starting feeling weak and tired.I urinate frequently.I bought a pregnancy test kit and tested it was negative,i placed the kit down and took it in like 4hrs later and it seems to be positive.I need help.Am confused.Am i pregnant or not?
