TMI HELP!

I'm not posting pictures of my boob on here. But right by my nipple, there's a red spot and it's hard and its sensitive. And its starting to travel up my chest. I've never been pregnant. Could it still be an infected milk duct? I'm currently waiting on my period, I'm spotting but no flow. I took clomid and provera last cycle. Just for extra info. Any advice? Experiences? Anything is helpful. I'm freaking out about it.
