So I had my period on the 3rd -8th and had unprotected sex the 10th and 11th . He didn’t finish inside me because he pulled out but I know that is still very risky .I took a plan b after the first time but not the second . Today on the 16th I started lightly bleeding even though it’s only been a week since I got off my period . This has never happened to me before . Does this mean I’m pregnant or is this a normal thing ? Should I take a pregnancy test and if so when ?
