Brief update after my visit to the doctor yesterday:
HCG dropped to 3.86, so below 5 and therefore okay.
I still have fluid in my uterus, looks like an amniotic cavity on the ultrasound, but it's not.
I am supposed to take Cycloprogynova from today so that I get a bleed and in the next cycle the Dr will do a biopsy of the GBM to make sure that everything is OK there. But he has two weeks vacation at the end of July and then we are on vacation at the beginning of August. A trip to DK in September is bad because of work or it would be really stressful. We have therefore postponed the next transfer to the beginning of October. It's much more relaxed then, in terms of work, you have to go there, the money has to come from somewhere
He also really advised me to wait until at least September to give my body the chance to recover.
