What is going on?

So I had my first pregnancy/first miscarriage about a month ago- had to take the pills to get the embryo out. I bled for like 2 weeks, after I got a “mini” period like a week later only for a couple days (I usually only bleed for 3 days). Now it’s been two weeks since that last little period, according to to this app, I should be ovulating this week, so my husband and I have been doing the BD every day in hopes of getting pregnant right away. I discovered at work today that I’m bleeding again and I’m not having any normal pms symptoms. I’m not sure if this is my body resetting itself and getting back to my normal cycle, or if I should call my obgyn. Has this happened to anyone else?
