Lining too thin

Je

Hi all. Am 2 weeks on estrogen 10mg and patches x 1 week. Lining only 6mm. Delaying the FET by a week and possibly will cancel cycle if no better on one week. They say will use injections in a subsequent cycle. Am disappointed and worried, thought getting the embyros was the hard bit. Didn't think we'd struggle to pit one back in. It is a bumpy road this thing. And there are hurdles all along the way😯
