Well I am now CD 31, still no sign of AF and HPT still BFN. the complication is, my back went yesterday - had to tell the physio I may be pg, so he could only do traction - no ultrasound or interferential. And no drugs like anti-inflammatories or ibuprofen. I wish I would just get a clear sign one way or th other. to be honest, wouldn't be too disappointed if AF DID appear. at least i could take some drugs!
