Help me

Let me break this down.. 

Last Friday: boyfriend and I fooled around a bit. Blowjobs, handjobs, fingering, but we didnt have sex because I was not ready for that in my life. He fingered me and I’m scared that he touched himself before going in me. He is typically really good at watching and making sure but we were in the moment and neither of us were watching carefully enough. 

Tuesday: I took plan b. After a chat with planned parenthood text line they said it could work up to 5 days after intimacy. So i took it to ease my nerve (didnt really work to ease my nerves) 

Thursday (2 days ago): 6 days after intimacy i was curious when i was ovulating so i went to my local Walmart and bought some ovulation tests. The Ovulation test i took Thursday and yesterday morning came out positive. 

And today the test line got a tad lighter.I am still a bit uneasy about if i could get pregnant or not. Any help would be appreciated. Sorry for this being so long.
