Condom came off

The condom came off and we didn’t notice. After he finished we realised it had come off and was inside of me. I’m not ob birth control and my period starts in a day or two. I’m not super keen on getting the morning after pill because the only available place atm is very small and quiet and everyone will hear me. I’m also 17 so they’ll probably judge..

Should i just suck it up and get the pill or will i be fine because my period is soon??

Update: i got the pill earlier and honestly 15 minutes of being embarrassed is better than worrying until i get my period or worse, actually being pregnant

Thankyou for the comments :)
