Im really super sorry if I may seem paranoid for those who answered my previous question already. My bf and I had unprotected sex on day of my period however he pulled it out after around 5 minutes, way before he came. After that day, we always used a condom. Today, on day 14 of my usually 35-40 day cycle, ive been experiencing sore breasts. Not really super sore but still kinda sore. Im having back problems (which I had before already) and kinda sleepy. I dont know if the sore breasts were a result from my recent exercises with no bra support. And also if it's because ive been taking extra doses of caffeine coz it's our finals. What do you guys think?
