Thanks everyone, appreciate your advice and experiences.

I had my blood tested at the donor centre. About 10 times! They were very persistent, but we kept getting low numbers. The dr today did send me for another BT, but gave me the gastro referral as well.

I have decided to wait for those results in a day or two and book for a different dr at the same clinic. A female, JIC. The guy today did ask me if my periods were heavier than normal. I explained that they were always heavy, no heavier than normal ...for me. But I'll stress to the next dr that my period is bad, but that it's been 5 years of pg and bf so things might just be getting back to 'normal', well my normal, whatever that means. I'll suggest that i would prefer a visit to a gyno before a gastro and see what she says.
