Hi Doctor, I Had Sex In The Last 24 Hours.

Hi doctor,

I had sex in the last 24 hours. At first, my partner's penis touched ny vulva without a condom. Before penetration, he wore a condom but in the wrong direction, so he couldn't unroll it. He wore the same condom in the correct way after few tries. I am very worried and scared now. Would there be pre-ejaculatory fluid containing sperms during the unprotected foreplay and also on the condom? Should I take the Plan B pill? My next period is due 17 days later.
