There are two issues:

1- Qatar is Islamic country and in Islam there is concept of Adoption,so you can not Adopt from Qatar.
2- If you Adopt some one from outside Qatar, you will not get Visa. You may need to change kids Father's name to your name in this case, which may not be appropriate.

Your original question is not answered here.

Moreover it is strongly suggested to see a good gynecologist, which you may have done before posting this, I suggest Dr. Zeenet Rizivi in Al-Ahli hospital, one of the best gynecologist of the country.

May God bless you with healthy baby.
