I don't think it can cause ITP but I know if you have ITP you are likely to have HELLP or PE in one form or another during pregnancy. PE and HELLP can unmask all kinds of things that you might be predisposed to having later in life, cardiovascular problems, hypertension, etc. Perhaps it is the same with ITP?
I hope the hematologist will have the answer for you.
