The booking in midwife was great. We left London between DC2&3 so I'm under a completely different team, now in Devon so Exeter is my hospital. I was actually booked as low risk to my local midwife unit. They kept everything low key until my BP suggested otherwise. As soon as it started going up I was whisked off for regular blood/urine/BP checks, each week, sometimes twice a week.
I'm in hospital now as I woke up on Saturday and knew something was wrong by how I felt. So I've been here 2 nights, will be induced next Tuesday at 38 weeks assuming it all stays ok until then. My bloods and urine are so far normal, slightly raised urea in blood, but BP sky high and headaches. So I may be discharged on medication to rest at home for the week.
You have to follow your gut and err on the side of caution really. I'm happy I made it so far without any problems. I'm worried about post natal care as my experiences in london were dreadful, but I'm hoping that at a quieter hospital and as I'm already well on their radar, it will be ok. At least they are well aware of HELLP, I've met midwives who didn't really know about it...
There are definitely different severities, mine was nothing like yours, far milder. Post delivery high BP and protein essentially.
I was most worried about premature birth and slow growth rates in utero, but baby's growth is fine.
Just see how you feel in a year or two or more, I guess. I waited until dd2 would be 4 when dc3 is born as I had a just under 2 year gap with the first two. I definitely didn't want a baby and child at home, now the first two are at school I have been able to rest a lot more than I otherwise would have. Worth thinking about the timing if you can, make it as easy as possible on yourself!! And think about how you would manage if you were ill for a month or two, with new born in tow plus 2dc. We knew no one when we moved here, luckily new friends have bee fabulous and we have 2 grandmothers who can come at a moments notice and help for as long as we need.
