SOS. Any chance I could be pregnant?

To start off, I've been on the pill for two months and I use condoms every time I have sex. I linked my pills so I didn't take the sugar pills so I never got my period. Now I am experiencing super bad cramps and pain in my lower abdomen and really bad back pain and I'm bleeding but not heavy just dark blood spots on my underwear. Barely enough to call a period. My breasts hurt really bad too. Is there anyway I'm pregnant? Does that sound like I'm pregnant? I have stopped having sex for a week and stopped the pill to let my body have a period but the pain is still there.
