Was your placental abruption in any way related to your lupus?
It seems so. I was told when I was pregnant with Findlay that prem labour, iugr, abruptions and stillbirth are all much more likely in people with Lupus

I think they told me pre-e is more likely in people with lupus too.
I don't take blood thinners as I don't have Hughes Syndrome as far as they are aware at the minute (tests for that have always come back neg so far but they test me every 6 months when I go down to the clinic) but I do take meds for the lupus.
My consultant in London did however tell the hospital Findlay was born at that I had to take Clexane for 8 weeks after Findlay was born. They did consider putting me on blood thinners when I was pregnant as I had retroplacental clots very early on that didn't resolve until about 15 weeks but they decided against it in the end.
I'm not TTC but if I plan to I have to let my consultant in London know so they can put me back over to seeing the consultant at the lupus pregnancy clinic there who I have to speak to before I ttc and then when I get pregnant I have to have regular check ups at the clinic in London, regular blood tests and regular growth scans. I have also been told that if I want to TTC in the future I need to try and do it at a time when I haven't had an active flare of the SLE for several months (ideally 6 months)
I saw a haemotologist at my local hospital in pregnancy and she was useless (not saying yours is btw just that mine was) so I never saw her again and just stick with the specialists in London as all they deal with day in and day out is Lupus and Lupus pregnancies.
Is it SLE or discoid lupus you have?
Hughes syndrome (aka Antiphospholipid syndrome) is a blood clotting disorder that can go along with Lupus but not everyone with lupus has APS and not everyone who has APS has Lupus
