Hi Nic,
Thank you for your writing your story, it takes so much courage to sit and write it all.
It also takes a huge amount of courage to plan for another child when you have already been through a trauma like PE.
I thought it might be worth adding to what they have told you in that PE is very unlikely to occur earlier for you as Caitlyn was born at 36+ weeks. If it is going to happen again it is likely to be at the same time of up to 2 weeks later and generally speaking is less severe. Mainly because you know what pregnancy is not supposed to feel like & that you will be so aware - nothing will escape being scrutinised.
As for the aspirin, the research shows that for mums who deliver before 35 weeks low dose aspirin is a good idea. But as you say, you were on the tail end when PE rose its head for you. The aspirin wont do any harm and if really necessary its effects can be reversed.
There is still the dilemma of calcium supplements too - again research shows that for most women of the 'western world' we get enough dietary calcium but if you know your intake is lower, then maybe thats an option for you too.
I hope this helps allay some of your worries & that we will hear happy news from you in the not too distant future.
Warm Wishes
Liz
