i also have positive results for ANA. but im not ni your shoes by a long shot. for me i was tested as part of the bloods done when i was pregnant with my 3rd. simply because the midwife I had at that visit asked about my mum who had high blood pressure in her pregnancies. so she did the ANA test as apprently its linked to hbp in pregnancy.
i went on to see the Ob who then did further tests whihc all came back normal. he told me though that a positive ANA can cause smaller babies & (sorry i know its not nice) a higher risk of stillbirths. BUT i never had any blood pressure issues & i didn't have small babies (my last was 9lb 9oz) so for me the ANA is simply one of the many strange little things that make up me.

so my post is really no help to you at all! LOL

But I will add lots of sticky vibes!!
