My general doctor (not OB or MIdwife) is who I see for stuff like that. I'm surprised you waited 2 months! I freak out when I find something like that (I've found two cysts in the last 3 years) and my doctor always has me come in immediately for a mammogram AND an ultrasound to confirm it is nothing.
Please call a doctors office (if you don't have one that you see - see who your husband sees) and have them schedule you right away.
I too have a family history of breast cancer (my Dad's mom and his sister had BC, and my Dad had a lump removed when he was young - noncancerous though). My Mom has a sister who's had BC twice...
It is probably nothing, but please don't wait any longer.
