I had a white mucus in my urine on 7th day after my transfer. Will it mean the embryos will not implanted?

IVF. That is hard to tell by only refering mucous discharge after insemination. Check with your doctor, consider an ultrasound. With all the medications that an ivf cycle involves its hard to tell at this moment if its a normal reaction or if there is something wrong going on. Tell your doctors your concerns.
