Does anyone continuously worry about their own health?

I keep getting triggered with things happening since I’ve had my baby 4 weeks ago . I got mastitis and instantly thought I had breast cancer, then I had high blood pressure reading a couple times and instantly thought preclampsia then I had a couple days of red bleeding and thought it was a sign I was going to hemorrhage. Every little thing that happens to me I jump to the worst case scenario in my head :(

Is this postpartum depression?
