would I get withdrawal bleed while pregnant?

So I suck at taking the pill. I didn't take it as consistently as I should've. I took 4 pregnancy tests, two of which were the electronic kind and all of them were clear positives. Naturally I stopped taking the pill. I'm about 4 weeks, I stopped two days ago. I know when you get a period on the pill it's not a real "period" it's just withdrawal blood, and I started bleeding today, about the same amount and consistency as my usual "periods" on the pill. Is this normal even though I'm pregnant or should I go in? The test I took tonight after I began bleeding was a strong positive as well. Any opinions would be great.
