Lumps with clomid?

Melisa • 35, Finally pregnant with #1 after IVF!! Due in May 💗
Have any of you ever had a lump while on clomid? This was my first month of using clomid, I'm on my TWW right now, and I just found a small lump in my breast tonight. I've never had one before and don't know whether to be worried or will it go away?
