Pregnancy risk


A week ago today was the last day of my period and I had unprotected sex. I took plan b right away just for precaution that same day. Last night while having sex the condom broke and he pulled out before he came. I’m wondering if it’s safe/recommended I take plan b again even though it would be the second time in a week or so. Now I’m close to the middle of my cycle and a little worried. Please help.
