How many pregnancy tests did you take before you believed it?

My sister took 4 and my aunt said that was stupid. After 1 you should be good. With this pregnancy I ended up taking 7. I took one at night and it was a very faint positive. So I took one the next morning and it was stronger but still faint. My husband didn't believe it so he went and bought a digital which then said not pregnant. So I took one more which was positive. Then I had an equate brand one which showed up negative. So I took one more line test and one more digital and one more line test which were both positive. If not for the 2 false negatives, I would've stopped at 3. How many did you take before you believed it? Was 1 positive enough proof for you?
