Fuller boobs??

My boyfriend got a little bit of precum on my leg and he wiped it off then he fingered me. (Or so I think) I was like 7% fertile according to glow. My period date is next week Wednesday and my boobs feels fuller. So far I'm not experiencing any other pregnancy symptoms I feel fine but I'm a bit worried I could be pregnant if he never wiped the precum off properly (as always I worry about every single thing). We did not have sex. 

Save your judgements please. 🙂
