Lost my baby on March 19..

My baby was born sleeping on March 21. She doesn't have a heartbeat on March 19.. I don't know how it happened. I got admitted on March 10 due to preterm labor due to UTI. My baby was too small for his gestational age. She was 35 weeks based my on my LMP and she was almost 27 weeks based on her ultrasound. Didn't know when my amniotic fluid broke. I only found out when she was not responsive anymore. I got her heartbeat checked via ultrasound and the result left me heartbroken. I got induced and delivered my baby normally on March 21. It was so devastating... I always ask myself why it has to be me... #stillborn #firstbaby
