could I pregnant?

I had unprotected sex, (I know stupid if you aren't trying to conceive) but I had unprotected sex on the 1st of January. My period last month was super weird. It last 9 days. 15-24th. I am currently 9 days past ovulation and do for my period in 2 days according to this app. I don't have any major pregnancy symptoms but today I checked my cervix and it is super high and soft. I also have a lot of white milky lotio like discharge on and off. My ovaries are kind of sore as well on both sides. My lower back in a little sore as well. I don't have any sore boobs or nausea though. Should I take a test?
