Losing hope of becoming a mother 😢

Back in January 2017 I had what was called prom which stands for premature rupture of the membrane at 17 weeks I was devastated!! I Prayed and knew I will eventually get pregnant again. Fast forward 2 years later I have a miscarriage at 6 weeks! June of 2019. 😢😢Lightning hit twice! Now I found out I'm pregnant now for the 3rd time and they keep telling me my Hcg levels are doubling but all they is a sac at 5 weeks. When will I see a fetal pole or a heartbeat??. I'm so lost I constantly think about what's going on. I just wanna be a mom. I don't care if I have only one child. That blessing will be enough for me. Please someone pray for me I go for my initial prenatal visit this Monday
