I had sex with my boyfriend just one day before my fertility window started according to the app. He was wearing a condom when we had sex but i stroked his bare penis and then touched his condom covered penis while trying to get it in (my hands weren't wet or anything )

Then we stopped PIV and switched to oral and that's when I took the condom off (hate the taste of latex). I possibly touched his penis and then rubbed myself. Now it's been 10 days and I have mild cramps ( I never have these) . I know there is always a chance. But realistically speaking is it possible I got pregnant? If so how can I know at the earliest?

Our only form of birth control has been condom and pulling out (together) and the only other time we had sex was a week earlier (on my period + condom + pulling out)

I am generally a paranoid person . But I don't know. I could have been fertile and if there was any sperm over his condom from my hands (even though it wasnt like soaked with precum or anything) I could have gotten pregnant .
