Has anyone experienced this?

I am 6 months PP so my cycle is probably still crazy. This month I got what I thought was my first real period since having the baby. I bled for a couple days a couple months ago, skipped a month, and then got a period. After my period I tracked my ovulation. I got a positive several days ago. This morning I woke up to cramping and bleeding. I thought this was odd. I took a HPT and it was positive. The thing is, I just ovulated and I am bleeding not a ton, but definitely more than spotting. I am going to the doctor to confirm but I don’t understand how I got a positive so soon or why I am bleeding the way I am. I didn’t experience this with my first. I hope the baby is ok. Has anyone experienced something like this before?
