Hello ladies!

I am new to using this app, and so far it seems awesome. I am hoping there are some women that are experiencing what I am experiencing. I am 23 weeks and 4 days today. On week 20 the ultrasound showed baby has a marginal cord insertion. Everything else has been ruled out (velamentous cord insertion, and Vasa previa.) My boy is growing well, and actually is a little above average. Their concern is it COULD turn into a velamentous cord insertion which could cause baby to bleed out when my water breaks. Has anyone else had this? How did your pregnancy go? Low birth weight? Complications during labor?
