Hi I'm 17 and got on depo a few months ago. I've had two shots so far and haven't had my period since I got the second depo shot. I was due around the time of the second shot. My boyfriend and I have had sex occasionally but not for the past month. Tonight I was standing in the mirror looking at my upper chest because of a clogged pore and I saw bright blue veins on the underside of my breast that I haven't seen before. The right side wasn't as bad as the left. I've noticed a lot of change with my breast as them getting bigger and I believe it's from the birth control. Are these veins just showing up because of that (I'm very fare skinned so I can see clearly) or is it pregnancy? I don't want to take a test if I have to. Thank you!!!
