Hi. I had my daughter at 25 weeks last July but a reason could never be found. I'm now 13 weeks with my second and my OB is putting me on progesterone pessaries from 14 weeks. Has anyone used them before on subsequent pregnancies? Do you think they made a difference? I'll be getting extra ultrasounds to check on cervical length and get a stitch if required. OB is hoping the progesterone will do the job though. Anyone care to share their experiences? Thanks
