Dear Maylin, don't despair. It will happen when it is meant to happen, God is great, and so is His plan. Trust that plan. Have you considered adoption? And if you find the services here are not helping you, can you go abroad for treatment? Considering, that might take more than a month and your husband needs to be with you too.
And do plan Umrah, pray your heart out. Pray that you get what is best for you. Please don't stress yourself out. Find activities that cheer you up. And foremost, focus on what you already have in life, feel blessed :)
Praying for the best for you.
