Not sure what pregnancy with a period looks like.

I can't remember the last time I had a period come early because I'm always regular and on time for the most part. I just had a period like a week ago and was not expecting to see it again for another 10 days. Today I was shocked to see blood. I already have a 10 month old. With her i felt pregnant and knew I was when I missed my period completely. I wasn't trying to get pregnant again. We used condoms but would sometimes engage in sex and he would withdrawal or would release on days that this app said I was the least fertile. I've heard people say they've had periods while pregnant. I just know the last time we were intimate like that was last cycle when it said there was an 8% chance of pregnancy the day after it said I was supposed to ovulate then I got my period (regular) 2 days earlier than I was supposed to and now I'm not sure what's going on. Not sure if it's spotting or an early period. According to this app my last ovulation date was 2 days ago and now I'm seeing some blood. Anybody have a pregnancy like this?
