Is pregnancy still possible in my case?

Hey I have read the question answers and I have scarleteen website but I am still scared, some people on the app that I use are saying it is still possible, please help me

so on Nov 23rd, we were dry humping where he was not wearing anything and I was wearing underwear and pad because it was day one of my period for November month. I saw some fluids on his tip and stomach when I was on top of him. after a few minutes I got uncomfortable and I got up wore my jeans back.

now I was worried about the the fluids touching my inner thigh and somehow making me pregnant. although it was day one of my period and I was wearing underwear and a pad. so I took two tests 18 days and 22 days after that incident and both were negative. later I got my period after a 29 day cycle. they were 6 days and quite normal I aslo clots and endometrial layer that sheds. but people say and google says that pregnancy is still possible.

my this month's period is late, is there still a chance, should I test again? also should I go to the doctor and get a scan, as getting negative urine tests is common ( people on the flo app told me)

I am very scared please help me.
