I've been taking the combined contraceptive pill for the last 3 years, but this month for the first time my breasts have been unbearably sore and tingling. It's lasted about a week, and I've taken two pregnancy tests that day I'm negative (it could be too early though). My nipples are also a little darker I think. I've never missed a pill and I always take it around the same time each night (within an hour). Am I pregnant? Because I've Googled loads and those symptoms seem particularly indicative of pregnancy; but I've taken my pill correctly - I'm 100% sure of it!
