im overthinking

me and my bf had protected sex on the 13th and then he rubbed his dick on my pussy the 16th but didnt put it inside and now its the 21st and im over analyzing everything. for example i have big boobs and i was bouncing them and there was mild pain and im thinking like is that actual boob pain or just pain bc their big? im supposed to get my period in 14 days and i know its to early to test but i can not be pregnant so please just reassure me im ok
