Hi @FearfulMommy, I am a midwife and deal with pre-eclampsia very often.
If and when you choose to fall pregnant again you will start with much more knowledge about the condition than the first time, and will be much more prepared. As Lego has mentioned, although having pre-eclampsia does increase your chance of having it again, the increase is small and plenty of mums go on to have normal pregnancies aftwewards. Having pre-eclampsia with you first baby is more likely than with second or third babies. One of the mums I gave care to had a horrendous experience with her first baby, with early-onset fulminating pre-eclampsia ending in eclamptic seizures... she was terrified of having any more children. She went one to have 3 more... no pre-eclampsia with any of them!
In New Zealand, where I practise, mums who have had pre-eclampsia before start taking aspirin and calcium supplements from early in the next pregnancy. It does not only reduce the chances of developing pre-eclampsia, but also protects your baby - pre-eclampsia can reduce the flow of oxygen to the baby through the placenta and result in babies with fetal growth restriction, aspirin improves placental perfussion and hence reduces this risk.
The recommendation with pre-eclampsia is to try to induce labour and attempot a vaginal birth if possible, as your body recovers faster after a vaginal birth. having had a CS, you can choose to have another one, however you can also attempt a vaginal birth for your second. If you need an induction of labour, instead of using hormone to induce you they will use mechanical ways to do it.
Feel free to PM me for anything I can help you with. Whatever you choose to do, you can do it!
