Scared I may miscarry

Brandy • 27 and the mom to 2 beautiful girls, Chloe Elizabeth and Mckenna Leeann 💕

So I went to my OB at 6 weeks and 6 days. But they are concerned bc the baby is only measuring 5 weeks and 6 days. They are concerned bc it’s measuring behind. The US tech shockingly found a heart beat, she said it must of just developed one. Even the doctor agreed. The doctor said she’s concerned bc I also been cramping. Which I know is normal too. I did with my first. But they are super concerned and making me go back Thursday. When I’ll be 8 weeks. She was like I’m not too concerned bc once they have a heart beat they are usually ok. But a big part of me know that’s a lie. I think they were sugar coating they don’t think it will make it. But maybe that’s me preparing for the worst. Anyone else have similar thing.

My daughter was two weeks behind but not till later in pregnancy.
