Need help immediately...pregnancy?

okay so i have had two experiences since wednesday june 15 that im scared about. the first was at around 1 am on wednesday morning i had PROTECTED sex (condom) with my partner. im almost positive he didnt bust and it did not last long only a few minutes if that. wednesday marks 5 days before my expected period.... im due for it tomorrow sunday june 19. the second experience i had very early this morning the 18th around 3 am when me and my partner were fooling around and things got out of hand. he rubbed his penis against my vagina quite a few times. he tried to put it in and thrust a few times but i told him i was nottt having sex without a condom so he stopped. i was so paranoid that i bought the morning after pill 8 hours later and took it. do you think i have alot to worry about??? i really need help im 18 and trying to make smart decisions by being safe.. im due for my period tomorrow and am FREAKING out
