I’m worried

So I know how sex works but I’m freaking out. I was messing around with this guy about 4 weeks ago & he never actually entered because my underwear was on, but he did cum when he was laying beside me. It did get on my stomach but I’m not sure if it got closer because the lights were off but also he did finger me later on. Again I know how sex works but I read online if any cum is near or on the finger then there still is a possibility. I got my period 2 days later but I haven’t gotten it this month & according to my tracker I should have started already. I’m stressing out because they say a virgin can still get pregnant by those scenarios. I’m just worried should I take a test?
