First time round I discovered at 14 weeks that I had a fibroid, quite close to my cervix. Also a low laying placenta which was apparently attached to the fibroid. At 26 weeks I had my first bleed, as part of the placenta had come away. All settled down fortunately, but I had 3 or 4 more episodes of sudden bleeds before she was finally born at 34 weeks. Scary times, it's not good when the ambulance crew recognise you.
With my second I also had a low laying placenta, but after several scans it looked like it was far enough away form the cervix that I tried for a VBAC. No bleeding this time, phew, but we still though he might make an early appearance. No, 42 weeks before I went in labour. 48 hours after my waters had broken I decided to opt for the C/S, having decided that pesky fibroid was probably in the way again.
On the up side, although both were scary I actually felt quite well and got away without morning sickness and the other usual pregnancy stuff. I'd love to do it all again but have been diagnosed with type 1 diabetes, not sure about adding that into the mix.
