a little scared 😿

im the one who always thinks of the worst first and end up scaring my self.. me and my bf had sex last on the 17th of may and i was on like my 3 placebo before my period actually started and he came in me .. and i ended my first month of pills i want two say two weeks ago, and im about to get my second one. im kinda freaked out cause i looked up pregnancy symptoms and one was the sore breasts, but the thing is its not my actual breast thats sore its my nipples that are only sore.. any advice?
