Benign Lump?

[StrawberryCola]

About 18 days ago, I noticed a lump in the outer, I suppose, edge of my left breast. At the time, I would have gotten my period, but due to wishing to not have a period for the month because of a vacation, I continued to take my birth control pill.
For the week of my "period", it was annoying. Just irritating and I knee it was there, but that could partially be mind over matter, but wearing a bra would drive me nuts.
I'm not coming to the end of my pack of pills and i will be having a normal period within 4 days. I have not had a problem with the lump in the past week or so.. It feels hard in places and maybe "squishy" in others. It isn't a stationary lump and it Definately moves around when I run my hand/fingers over it. Now, the shape is more ovular than round.. I guess you could say its like the edge of my breast tissue, but that has been filled up like a "lip".
From research, it seems like it could be fibroadenomas. I'm not overly concerned, but it'd be nice to have some medical input.

Thanks.

Ps. I'm only 19 and I have absolutely no family history of cancer in any form and in every appointment I've had with my doctor, she has never found anything.. this is just recent and appeared within the time I would have gotten my period.

Dear StrawberryCola, Over the internet it is impossible to say what this lump is.  A new lump is a finding that should be assessed by your doctor.

Edit: I will NOW be coming to the end of my pills

Then why have an "Ask a Doctor" forum?! Assess other questions, but not mine? Ridiculous
