Am I pregnant??

Hello . Knew to all this. I'm VERY confused. Ok so I stopped my pill on the 12th of April and had the withdrawal bleed a few days later lasting around 5 days I then had a 27 day break and had a period for 5 days then it stopped for 2 and started again and it's light but pretty much filling a pad and will be a week tomorrow that I've been having this bleeding the confusing part is I have had 4 positive pregnancy tests since yesterday. Am I pregnant?
