Advice and feedback please Ladies ❤️

Hi beautiful people! So on December 5th I had sex, my period started 3 days after (as expected) and I am birth control however I had missed a couple of pills approx 2 in a month, we used a condom and i’m pretty sure it didn’t break nor do I think he cummed fully. However, today here I am on December 27th and am experiencing slightly sore breasts and feel very tired... I can’t tell if at this point i’m just freaking myself out or what. But any advice or input would relax my mind and be much appreciated. What do y’all think? And next period is supposed to start in 2 weeks. Thanks babes ❤️ i’m nervous
