I recently missed 4 birth control pills and had unprotected sex. I spotted for two days and then my flow has gotten heavier like an actual period. My real period is not supposed to start until Sunday. Is there a chance I can become pregnant? Should I expect my scheduled period to arrive? If I miss it am I pregnant?

Any time you have unprotected sex you could be pregnant.

The flow is "probably" a result of the missed pills.

No, your "scheduled" period probably won't arrive.

I doubt you'll "miss it."

This is unfortunate if you are trying to get pregnant by skipping birth control - but I doubt you are.

Could you be ? Yes maybe, I don't think you are, I think this will just be your regular period as a result of missed pills. But then it could be also.
