early miscarriage (abnormal uterus)

Jules
30th november i finally got a BFP i started getting symptoms and booked an appointment with my doctor to confirm. Tuesday the 1st of november i woke up bleeding, and with super painful cramps. I just knew i was losing our baby. We went to the doctors and my cramping got so bad i started throwing up. They are rushed me to the emergency room where they took some blood which said my HCG level was only 16 :( 
I had to go back today for more blood work and i dont want to feel false hope but i have heard that some people s HCG level could spike back up.
Im still bleeding like a period, and also i was informed i have a abnormal uterus (heart shaped) 
Anyone experienced anything similar?
