Rhesus negative with antibodies

Hi, I've got my blood tests back and found out I'm Rhesus negative but they've identified an Anti-M antibody.

The midwife didn't know anything about this - just referred to some weird "gunk" on my results - helpful!

I'm 18 weeks with my first and had a miscarriage at 10 weeks last year - which is where the antibody developed I assume as I've never had a transfusion.

I know I'll need the anti-D shot at 28 weeks but I'm just want to know more about the potential effect of the antibody. I've googled and read some mixed things.

My actual notes say:

O RhD negative C-c+E-e+K- (this is the gunk the midwife mentioned!)

Antibodies identified:

Type: Allo
Specifically: Anti-M
Technique: Detected by IAT only

The antibody is clinically significant but was not titrated as it is not reactive by IAT performed strictly at 37C. This antibody is unlikely to cause haemolytic disease of the newborn. Guidelines recommend repeat screening at 28 weeks (prior to anti-D administration).

Sorry for the war and peace - but I just want to understand what this means. I'm assuming it's not a problem from what they've written. I've booked an appointment with my GP to be on the safe side (my midwife fills me with no confidence on lots of different counts) - but just wanted to pick the brains of Mumsnetters as well.

Thanks in advance for any help you can give.

I don't know much about this (although there is someone who posts here who does) when you see GP you should insist on an appointment with a specialist to discuss implications. It does sound like they are not especially worried about it
