Idk what to think weird

Raelea.

I’m 10 weeks haven’t had a period since April 7th and I started spotting so not normal for me I’ve had two other babies and I never had spotted I wanted to get checked out just Incase right well it get this is where it weird I go in they tell me we are going to check your pee and take blood ok normal and my count was up to 13000 so that was good and my urine was clean so no infection and then they looked for a heart beat couldn’t find it did an ultrasound they tell me that my baby is the size of a 5 week old 0.0 so it stopped growing and this isn’t a viable pregnancy ??? Apparently it might be but I’ve been pregnant for ten weeks I tested the beginning of May positive how is that possible I’m scared and confused and honestly down right sad
