Hey guys ... tonight me and my boyfriend had sex .The first time didnt use a condom and he pulled out just before he came.He said he didn't come in me .After that we had sex with a condom and it broke . This time he didnt come in me too . But there couldve been sperm or precum idk.Its the 14 day of my cycle and my period is in 8 days .He says i shouldnt worry but im kinda stressed and i consider taking plan B ..although that might be bad for my health (used plan b 2 times the last 5-6 months). So what do you think ?I really need your help , plz😢
