My right nipple is constantly hard and my boob hurts constantly

Hey y’all!

I’m kinda nervous as to why my right boob is constantly in pain and the nipple is always hard? I’ve had an untrasound and mammogram done recently and all is good. Feeling no bumps and no lymph nodes swelling (praise god for good health! 🙏) also checked out great with annual female exam.

I’m not pregnant and am TTC. This pain has been going on for months. I’m currently only one day late but I’m convinced that’s my period teasing me.

I did take fumera last month only for one month cycle (hated the side effects especially the weight gain!)

Anyway any thoughts ?
