Breast Lump that Wiggles

I am 27, and currently breastfeeding my second son. The day after Christmas I discovered a lump on the lower, inner portion of my right breast. It is about 2 1/2 centimeters in length. I know more serious lump aren't supposed to move around, my lump feels attached, but if you touch it you can wiggle it about a centimeter or so. Does that count as moveable? I know it isn't a clogged duct because I've had a few of those before, so I'm thinking perhaps this is a Fibroadenoma? Anyhow, my DH was laid off and we don't have health insurance right now, so any advice is greatly appreciated. Thanks in advance! :)

Dear Bostontaggmom:  Without evaluation, it is impossible to speculate on what this may be or whether additional investigation is warranted.  You don't mention how long you are postpartum but do you have any follow up appts with your OB?  Perhaps he/she could do an examination.
