My boyfriend and i had sex that was unprotected, so i used plan B and i bleed for 3-4 days, but after that week we had unprotected sex again and he didn't cum inside me, and i took a pregnancy test 7 days after and it was negative, but that might have been too early to tell. Is my period late from plan B or pregnancy?
Plan B can make your period late, or early, and heavier or lighter than normal.
You need to wait at least 2, preferably 3, weeks after having sex to take a home test. If you do, use ONLY your first morning urine for the best accuracy.
