Anxious and scared (probably for no reason)

So me and my guy friend were messing around yesterday and he had a condom on and everything but we tried a couple times I sat on him and everything but it didn't really work out so we just resulted to fingering and blow job. I'm scared that maybe some Precum got in me when he fingered me after he like readjusted himself although we have been in this position before and nothing happened and I got my period. However I am nervous because I recently started bc the begin of December and on the first day of my period like my doctor said and my period was supposed to start today but it's normally a day off of what <a href="https://play.google.com/store/apps/details?id=com.glow.android.eve">eve</a> says. I have had my normal pks symptoms but I am scared I might miss my period because of the bc. I am on lo loestrin fe and I feel like I should have waited until a couple months before me and him did anything. Should I go get a test or is this more of my anxiety just telling me something is wrong ?
