Pregnant?

I have a really dumb question. I am a married mother of 2 (3,1 1/2) i am on a birth control pill but I haven’t had a real period in 2 months now I bled for one day that’s it and have taken 6 test a random days through out this 2 months and I don’t have a doctor or anything because my insurance situation is crazy right now so I don’t know what to do but I am so terrified we are in no way ready for another baby. But my question is it my Birth Control messing it up or does it sound like I should go to the Doctor
