Holly • For this child I have prayed; and the Lord has granted me the desires of my heart. 1 Samuel 1:27
Has anyone on here had the ability to conceive easily yet they are unable to carry the baby to full term? Currently I've been through 2 miscarriages one in March and one just this month. 
My first miscarriage was due to it being an ectopic pregnancy; this go around she seems to believe my body just absorbed the fetus after it stopped developing. 
Any helpful advice or tips are welcome because as we all know as a woman we like answers... Or at least feedback from someone whose experienced the same or similar situation.
 The doctor did say she thinks it could be my proestrogen levels or it could be chromosomal. Please help my grieving mind ease a little I've prayed but I'd love to have some support from you wonderful ladies!
