Tragic Sunday

Me and my boyfriend were having sex but when I got off him he notice the condom was missing. The condom was stuck in my vagina 
The good thing was we notice and he help me remove it. We are so scared! 
Worried that we call a CVS Pharmacist 
She told us to buy the Plan B as soon as possible 
I took it but still worried! Can someone give advice!😭😭😭😭😭😭 Ps he didn't didn't cum
