don't judge

Feeling queasy and hot these past couple days but I haven't had any sex. Me and my boyfriend were messing around the other day like fingering and stuff and he came in my hand and later that Night i fixed my underwear. Is there Any chance i could be pregnant? I mean it sounds silly but I don't know things happen. Yes the fly has been going around but I'm just trying to stay catious you know, so is there any possibility ???
