One of my pastors said something interesting sometime ago, he said

‘If you have a yam seed that is not enough to satisfy you, instead of wasting it, plant it’. When you plant it, it germinates and gives you so much. He was actually talking about sowing seeds.—– What do you have that is not enough for that pregnancy treatment, that IVF, IUI etc. Take another bold step and sow it to God in your church, place of worship, an Orphanage home etc believing that God can turn it around and in turn bring forth your baby. However, you must work on yourself first, your heart has to be ready, do it willingly with joy in your heart. Do it sacrificially, rejoicing at the returns that will come your way.
You send your seeds on errands, you do not just drop them. Mind you, the devil will always tell you something different, contrary to your expectation. 1st Kings 17; 7-16 Talking about the widow of Zarephath.

10 ‘ …. So he went to Zarephath. When he came to the town gate, a widow was there gathering sticks. He called to her and asked, “Would you bring me a little water in a jar so I may have a drink?” 11; As she was going to get it, he called, “And bring me, please, a piece of bread.”

12 “As surely as the Lord your God lives,” she replied, “I don’t have any bread—only a handful of flour in a jar and a little olive oil in a jug. I am gathering a few sticks to take home and make a meal for myself and my son, that we may eat it—and die.” Read up the rest of the story. She ended up giving it to the man of God and her world was transformed.
There is no way you give to God in good faith and not get your reward. Let it be between you and God who rewards in the open. Think about this and take steps. Your baby must come. U r a mum/dad in Jesus name.
