Ejaculation Question.

My boyfriend wiped me off after fingering and then ejaculated on the other side of the same towel. I’m really worried that fluids got crossed. I’m supposed to get my period on or around the 11th-ish. Should I be worried about pregnancy? This happened yesterday and today I’ve been kinda bloated and have had to pee a lot more frequently. Please answer honestly and do not be rude. Not everyone has access to proper sex ed. should I take an emergency contraceptive?
