My platelets when I went in with HELLP were about 50, by time I delivered they were at 30K and falling after the emergency c-section. So I had 2 platelet transfusions too. But even with those, mine weren't up in the normal ranges by time I left hospital but they tested me afterwards to make sure they were going up on their own. I too had it tested at 6 weeks and about 4 months after delivery to make sure it was normal. For me, even after 1st transfusion, I still wasn't feeling well and had bruising all over my body, so that is why they decided to do second transfusion. Once that 2nd one happened, I finally started feeling better. So in addition to testing at normal intervals, make sure you tell your doc if you are not feeling well or bruising easily a few weeks out.
