Babyplease: glad your bleeding seems to have stopped for now! You must be a bit less worried now... TBH I have not been too worried about chromosomal problems, but as 2 gynaes siad in my situation it might not be a bad idea, I decided to get the test.
Sapphire: you must be looking forward to your next scan too!
Beattie: my UK clinic needed recent blood works, including AMH, hormones, thyroid, check of vit D (as first bloods showed extremely low values of vit D, so I took supplements), and of course infectious diseases. I also had an US on intake, where they checked my folicles. In Belgium I had already had a HyCoSy (standard before IUI's there), which showed there might be a problem and showed a polyp in uterus. Hysteroscopy confirmed polyp, so they decided to remove it under GA, and at the same time check tubes during a laparoscopy (which turned out to be fine after all). Don't know if UK clinic checks tubes on everybody prior to IUI.
Josina: fingers crossed for your new attempt!
