I just had a baby 8 weeks ago and I ended my last period about a week and a half ago. So I started taking birthcontrol again until I get on the shot and I'm still sexually active w/ my boyfriend and as I've been taking this birthcontrol I've been bleeding kind of like a period? Is it possible that I am pregnant or just starting an early period due to the birthcontrol

Most likely it is due to hormonal changes following the pregnancy and starting the birth control.

However, any time there is penile insertion into the vagina pregnancy is a possibility. No form of birth control is 100% effective.
