Should I be worried about pregnancy?

Hi, my gf ovulated last Sunday since she told me she had some watery and clear discharge and on Monday it turned to white and dry. It was her first ovulation after 5 months since she has PCOS. We had some sexual encounters on Saturday (day before ovulation), we don't do intercourse. I remember we dry humped and after dry humping I kinda kissed her pants, underneath is the vagina, was just teasing her. Then I drank water, after about 20 minutes of rest, we made out, I performed cunnilingus on her and after she was satisfied, she gave me a head. There are things that I wanted to ask.
I'm kinda worried if there were sperm in her pants where I touched or kissed then I ate her. Also if sperm can pass through clothing. And if some sperm in mouth or in my hands when she rubbed thing with my pants on, then to her vagina. I didn't cum tho not until she gave me a head. (I wore my clothes all the time and just removed it when she gave me a head, in the last part of the scenario). And yeah, I know my pants weren't wet or saturated with precum or sperm. Just my head is going crazy cuz I'm really anxious.

Is pregnancy possible in the scenario?
