What are the possibilities of getting pregnant from precum while on birth control (lowest dosage)?

I am on the lowest birth control dosage cause I got diagnosed with cysts in my ovaries(possibly pcos). I had unprotected sex on 12/21/19 (he didnt cum in me) and I had unprotected and protected sex on 12/31/19(once again, he no cum in me). I take my pills exactly on time and I've never missed a pill. I am very paranoid of getting pregnant cause tbh me no want kid but tbh I'm also very dumb. So I just want to know your opinion if its possible for me to get pregnant like very possible, probably, or not possible.

Also please let me know if you think I'd be pregnant. I havent had any symptoms besides soreness afterwards.

Please be nice too😅 have a happy new years!
