How likely could I be pregnant

So I had protected sex before I started the pill with a condom and he pulled out . And I do realize the symptoms I could be feeling are due to the pill. However I’m still paranoid and I “feel” like I’m getting my period but according to my app it’s 12 days away which is the 4th week of my pills . But 12 days is kinda to early for PMS symptoms I feel cramping etc .
