Breast lump? What to do about it??

I'm really worried. A few days ago I felt a small bump on my right breast, it's irregular shaped and about dime sized. It doesnt really move when I touch it and is slightly tender, but I'm not sure if that's because I keep pushing it since I'm worried or if I'm imagining it's tender. I'm only 19 and I've been trying to figure out what it all it could be. I was trying to cut back on caffeine, and I read a few things that said caffeine could cause cysts, but since I cut back about 2 weeks before I noticed this it leads me to believe it isn't a cyst and so far most of the symptoms are more of the cancerous symptoms rather than cyst symptoms so I am freaking out, but I am young so I just don't know. I just moved here and I don't have a dr yet, so what kind of dr should I see, a gynecologist or what?
Also I just switched to Jolessa birth control (seasonique generic) from Tri-sprintec and so won't have my period for another 6 weeks. I saw some people recommended others to wait until after their period to see if it goes away but that is a while to wait, so I don't know what to do...
