Help!

I've taken 4 pregnancy tests, 3 tests with lines and one digital. The digital one gave me a BFN but the line tests gave me two extremely faint positives and then a slightly less faint positive.  I'm 19 and my boyfriend is 18, I was on birth control but had recently switched from the IUD to the pill. During the first few weeks, we were using condoms to be safe and we had a condom break and now I'm not sure if I'm pregnant or not. I'm lowkey freaking out and I don't know what to do. I know that I can take care of a child, I'm very financially stable, with around 16k in savings, I've got 2 jobs and I already go to school online so a child wouldn't interrupt that. BUT my boyfriend, is not ready. And thinks his mother will kick him out when she finds out I'm pregnant. I'm worried and I don't know what to do. I'm going to the doctor to confirm my pregnancy, but I'd like to hear people's opinions. 
UPDATE: The digital test that I took was the First Response Gild Digital. I've heard that those tests have problems and tend to not to be accurate? Also, I'm only 3 days out from when my AF is due.
