pre cum from dry humping please help

me and my bf were dry humping but we were only in underwear, he was in his boxers and i was in a thong but it was kinda pushed out of the way. He was pressing his penis against my vagina through his boxers. he didn't ejaculate while doing this but i'm worried about pre ***. he also rubbed his penis a few times and a few minutes later he fingered me. i am on a combination pill but i take it at different times at night (about 6-11pm), i've been cramping lately and i'm so scared to the point where i'm not eating. i have 2weeks left until my period is due and i had some cramps prior to this encounter so i am worried that maybe i was ovulating. i am scared bc i have heard that taking the pill at different times could be bad and i'm really scared. could i be pregnant?
