So I came back to the gyne on Nov. 4, to know the result of my biopsy it has immature placenta with hydropic change and deciduals tissue so after that the gyne said i need to transv. To know what hyropic change mean. And then on my utrasound is normal size uterus and ovaries. Thick endometrium. The doc. Give me methergine to contract my uterus and expel all the tissues she said. And then on Dec. 3, 2016 i had my period but it is light not heavy,and after the red change it to brownish . And it last until Dec 17. So i go back to the gyne and i had ultrasound with thick endometrium too. The doctor said i need a d and c again to clean my endometrium.
