Nipples hurt with any pressure??? Wtf??

Reanna
So I had sex with a guy a couple weeks ago and the condom broke but I figured it wasn't much of a biggie because I'm in birth control (the implant) and rarely used condoms with my ex and never had any issues, and now my now my nipples have been hurting from literally any pressure at all for the last five days. At first, I thought maybe they just got irritated because I had jus got a new bralette so I figured maybe there was something in the fabric that my boobs didn't quite agree with, but here we are five days later and they still hurt whenever there is any pressure at all on them, and I'm starting to freak out. Being pregnant really isn't an option for me (that's why I'm on birth control) and I'm still in college trying to major in physics, should I be worried and making an appointment to see my gyno? Or has anyone else had issues with this and it wasn't a big deal? I was nearing the end of my period when I last had sex, and my cycle is obscenely long, if that helps any.
