This is deepiiiiii
Let me tell you the lord actually heard your cry/prayer for children but clearly there are powers terminating your pregnancy :
1. Perhaps, either you or your husband has committed abortion in the past & now the blood is crying against your womb hence the termination(spiritual abortion).
Yes you are right there was a conceive child in your womb but it's been terminated.
2. Or : powers from your husband foundation/family are definitely beyond your mystery. Listen, if indeed it's in this case note that you are ok,the infliction isn't from your side but your husband's.
Solution? Sit your husband down,dig your past and see if indeed the case is number one. If that's it? Call me as I will guide you on our to go about your confession and shut the mouth of this blood crying against your womb. Well. Perhaps it could also mean that in your husband family someone committed or took 3lives hence crying against your husband lineage,and it's affecting you now.
if after you make this above mention effort but couldn't find any of these coming from your husband or you?
Then, continue with the procedures given to you while you add : oh lord, what can be done to overcome this power terminating my unborn children,troubling my womb. Couple with the former prayers, ok?
There is a deep secret surrounding this infliction terminating the children in you womb you are not barren at all,hence we must find out before we know what to do.
Bless you.
