For me this is my second high risk pregnancy, my first was classed as high risk due to:

Polyhydrominous (high amniotic fluid)
Septate Uterus
Low Platelets

I went through an OB and ended delivering prematurely at 33 weeks, due to a PPROM and Spontaneous Labour quickly followed and wasn't able to be stopped, had a VB with an episiotomy.

This Pregnancy is high risk due to the following....

Previous PPROM (pre-term rupture of the membranes) and PTL (Pre-Term Labour)
Septate Uterus
Multiple Pregnancy, with early loss or twin
Possible IC (In compentant Cervix)
Low Amniotic Fluid (which appears to be settling at the moment !)
Possible Irritable Uterus
Placenta over the septum of the uterus and abnormal appearance to the placenta, with risk of SGA (Small for Gestational Age) or IUGR (In Uterine Growth Restriction)
Low Platelets
Prolapse

I am having fornightly scans on my cervix to monitor it's length and whether it is staying closed, we have had over 2cm of shortening over the past few weeks, and have two more scans with the opportunity to do an emergency stitch if needed, we have just over 6mm left before it become critical, next scan is next week.
I have had my first lot of Uterine Dopplers to monitor blood flow through from the placenta and cord to monitor and changes which could indicate the beginnings of growth restriction.
Keeping track of BH's length and frequency and any cramping to ensure that they aren't increasing in intensity and frequency.
Four weekly BT's to check platelet levels.

I am seeing a Private OB who speicalises in High Risk Pregnancies and I feel that she is doing everything she can to ensure my pregnancy lasts as long as possible, I feel that I am in the best hands and that I am confident that we will get as far as we can and what ever gestation that is I am at peace with what ever the result is. She listens to all of my concerns and is being very proactive.

I am booked into my Private Hospital and the Hospital where I had DD should I not make it to 36 weeks, so I feel comfortable that we won't go through what we did with DD.

If my cervix shortens too much after it is too late to do the stitch she will be starting me on Progesterone to hopefully stabilise it, and Nifedipine to relax the uterus/to stave off contractions, and the steroids would follow incase we got to a point where we were unable to stop everything from progressing, as we need 3 courses over 48 hours to be really effective.

I have good and bad days, I feel that somedays I will easily make it beyond DD's gestation then i have days when I feel that I will struggle to get a few more weeks, it can be such an emotional rollercoaster, and I am focussing on 30 weeks as a big milestone to get past, the smaller milestone of 24 and 28 weeks are in my mind but not at the forefront as I feel that while the baby has a good chance at these times, the journey can be a very rocky one, the longer we can bake the better and I feel that I need to focus further ahead. After 30 weeks I am aiming for DD's Gestation and then 36 weeks and of course full time

I will leave it at that for now, and see if anyone comes in and joins me
