What are chances of pregnancy and why interrupted bleeding occurred?

There's no way to diagnose on the internet. If you're concerned about the "interrupted bleeding" you'll need to discuss this with your doctor.

You're having sex, so yes, pregnancy is possible. Are you? Don't know. We can't diagnose pregnancy online either. You'll have to wait until you miss a period, and test at least two weeks after a missed period, using first morning urine.

Good luck.
