Loula I am sorry to hear its taken so long to get to this point of pregnancy and I can understand your anxiety and fears for this baby. I have absolutely everything crossed for you for a smooth sailing second and third trimester. Hope the spotting ceases (for piece of mind) and the weeks fly by. With your history and difficulty concieving I would imagine your Ob is more then obliging (or should be) to monitor you more closely then neccessary just to keep an eye on things and for some reassurance for you. If in the event your cevix appeared to be shortening they could offer you a cervical cerclage/suture provided it wasn't too short or sometimes nifedipine and bed rest. Obviously its not something that would or should be offered due to the risks unless the benefits outway the risk IYKWIM!

crumpet and Minky I am so sorry to hear that your beautiful bub's were born to soon. I wish things were done differently to change the outcome. Hugest

As a midwife I have only seen one lady have a suture put in (that didn't have a past history of second trimester labour/birth) based on an ultrasound which showed funnelling and shortening of the cervix. The rest have unfortunately all had past prem births. Fortunately our Obstetrician is very good at the procedure and to date have all been successful in prolonging the pregnancy into the third trimester. If like you Crumpet the cervix is already dilated too far or the membranes coming down to far he can't do it.

Loula the subchronic haemorrage seems to be one of the more common reason for bleeding/spotting in pregnancy.
