Drop the pill

I have an issue and needed some opinions. I stopped taking my birth control about 2 months ago. I have been on it for years due to irreguar cycles. I have been having a hard time with it the past 2 years so I decided to stop it. The issue is, I have had one period on time and regular but now, this time I am 17 days late. I have taken 3 test only to get negatives but I'm bloated, have light cramps and have a lot of discharge. I dont want to waste time going to the doctor if I'm just reacting to the lack of bc but I don't want to be unprepared for a baby if I am pregnant...is it possible I am pregnant?
