Is it too soon the tell?

So I met this guy on tinder last week and we really hit it off. We doesn’t everyday of that week together before he had to go home for winter break.

Before him, my dry spell lasted about a year so I’m not used to sex at all. We had sex about 3-4 times and I cant tell if what I’m going through is because I’m pregnant or if it’s just my body adjusting to the new sensation.

(Idk if this matters but when he was fucking me I could literally feel him press against my cervix or something, like a wall..)

The first time we had sex we forgot a condom so I️ used plan B about 30 hours later. About two days after the second time we had sex, I️ noticed light cramps in my lower uterus, like pressure almost and cloudy urine. My vagina seemed off and I was in a really good mood then tired. My vagina also started itching and burning for a few days but the pain was a solid 3/10< It’s about 5 days post-seeing him and my lower uterus still has some pressure at like 15-20%..
