Esrogen pills to thicken uterine lning?

Jessica
So my uterine lining is VERY thin & I'm not getting periods. Ever. No periods for three years. My doctor put me on 28 days of estrogen & the last tens days of them I also take provera. He said it should build my lining then make me bleed. Anyone have luck with this? He wants to try clomid if period comes from this treatment.
