possibilities of pregnancy

hey guys,
this is going to sound absolutely ridiculous, and I know it, but let's just say I'm a huge worrier and focus on the negative/small chance of anything. so on the 7th day of my cycle, which was the day after my period, I got together with this guy and did some sexual stuff but we didn't have sex. I'm a virgin actually. but, I gave him head, then he went down on me but then he leaned over and started making out with me and his dick tapped my clit area twice. he didn't cum yet because he did it after when I blew him again. i have a longer cycle than most but it can be irregular. it is usually either 32-36 days and once it was 42. now, it's a week and 2 days after we did anything. <a href="https://play.google.com/store/apps/details?id=com.glow.android.eve">Eve</a> says my fertile period starts tomorrow and ovulation but ovulation usually starts days 14 but since my cycle is longer, I'm assuming ovulation happens later or at least not earlier. I'm just wondering if there is no chance or basically 0% of having a splash pregnancy. again, i know I sound crazy almost for even worrying but I'm a freak about this stuff, super careful, and again a huge worrier. I'd love some input, thanks.
