I need help ladies!

Okay so I've been on and off birth control for over a year. The first time I was on it for a few months then stopped taking that brand at the end of the pack, my period returned within 32 days. I was off the pill for a few months and my cycles range anywhere from 28-32. The second time I started with a new brand, on it for about two months then ended it again and my period returned within 30 days and I stayed off for a few months. Now I took one pack of that same brand and then ended again and now I'm currently on CD 40. Could I be pregnant? Yes I did do the deed the month I wasn't taking the pill. Please help!
