Could I be pregnant?

[MaliaLia88]

Hello.  About seven weeks ago I was on vacation.  I had been trying to stretch myself and didn't want to lose days so I was fingering myself in the bathroom.  One of my fingers accidentally slipped and touched the bowl.  I wiped it off and continued, thinking nothing of it.  However now I am freaking out about this.  If anyone masturbated in the bathroom, it wouldve been at least forty minutes prior but likely more time had passed.  The toilet had also been flushed at least once and the shower had been used so there wouldve been temperature fluctuations in the room.  Is there any chance I could be pregnant and, if there is, how likely is it?  I read somewhere that cold water, tap water, temperature fluctuations, and exposure to air will kill sperm but I have no idea what sites to trust.  I am stressing out over this a lot so any response would help.  Thank you so much
