Two miscarriages

Brittany
Hi all! Just got my bfp today (CD24) but afraid to get excited....had two missed miscarriages in 2015.  My body held onto them until about 8-10 weeks, even though the babies stopped growing around 4-5 weeks. Is anyone else finding themselves almost expecting heartbreak? I want this baby to stick and survive so badly! But after two pregnancies in a row that ended, I'm so afraid this will be the same outcome 😟
