Has anyone had marginal insertion of the umbilical cord? Did it cause lower birth weight or no? My OB told me today that I have that and that I'm going to have 2 more growth scans to check that the baby is continuing to gain weight and grow on track. 20 weeks on Tomorrow and so far she's measuring perfect with my due date. He didn't make it sound definitive that it would cause low birth weight, but he said it's common so now I'm curious 🤷🏼‍♀️ not worried, just curious lol picture of our first little girl after 3 boys 💕
