Please, I need advice! Antibodies in blood!?!?!?

So I’m 31+5 weeks pregnant and at my midwife appointment yesterday she told me that some antibodies had been found in my blood and I needed to send off more blood for testing as they are unsure what it is.

I have been told I’m going to have to deliver my baby at a special unit in the maternity hospital now.

Has anyone else had something similar?

They can’t give me any more answers until my results come back.
