Could I be pregnant?

**Sorry if any of this is too graphic**

My boyfriend recently came to my state from across the US and I was wondering if I could get pregnant. Let me explain it as well as I can. On around Sunday I was giving him and handjob and he was fingering me. He touched his penis (did not ejaculate) then started to continue to finger me. I was curious if him touching his erect penis then touching my vagina could get me pregnant because I read that an aroused penis can still produce precum. My period was due on Sunday but it's usually late by a few days anyway. (Its Wednesday now) I'm cramping a little bit but not as much as usual and I had very little vaginal dischargw yesterday and its sticky, clear today. I'm not sure what that means because I haven't really paid any attention to it considering this is the first time I've ever done anything with anyone. I'm also 19 years old. Thanks for any help!
