@Ragman,
I was blue too - but that wasn't an Rh problem. I haven't read up on blood types since my days as a beginning lab tech, but I remember a lot of sturm and drang about the difficulties with the incompatibility. I think JPB is really knowledgeable about all that, and Butrflynet's points well taken.
On the symptoms - it could also be a bleeding fibroid, and sometimes those are small, thus probably hard to detect in an emergency room situation.
What I'd suggest nikkie do is see a gynecologist to figure out what it going on. And Punkey is right, re the tiredness possibly being due to anemia.
Edit - I just saw the date re 1968 - I had stopped memo'ing all the data re blood types back in '65 after my boards tests. Glad to know this is much less of a problem now, though it makes sense since we don't hear of that so much anymore, at least in the news.
