Late 2 days! Im scared, advices please?

Puggie

Hello, guys, sorry for my idiotic question but Im scared and paranoic because a month ago I took the plan B. My period came and lasted 1 week, but is was pretty weird, like... more spotting than period. Though, I had cramps and days when it was very heavy.

This month, it should've come two days ago. I am in a trip with my family and i swam (hope its correct) and thought that may be a problem.

I had unprocted sex with my bf, but he came in my mouth or on .. me, nowhere near my vagina and we didn't cross any limits..

So, could I be pregnant?

I am 19, and tommorow I will do a test when I go home. but I need some advices bcz im pretty paranoic and scared.

Thank you!!
