Quite upset to know that you lost three pregnacies!
You have taken a great risk by becoming repeatedly pregnant.
Pre-eclampsia is a dangerous disorder related to pregnancy
when patient's BLOOD PRESSURE shoots to supraphysiological range and there is albumin
lost in urine and edema feet due to fluid retention and if accompanied with convulsion
it's called Eclampsia.
It carries high morbidity and mortality for both mother and the fetus.
I would advise you to adopt a child rather than to procreate.
Anyway if you want to take risky route then I would advise you to get in touch with a good physician for through out pregnancy managing the hypertension
and not when you develop symptoms.
A good follow up with a sensible Physician And Gynecologist can help you through this challenging disorder.
