Prayers for a viable pregnancy

Dear God,

I have been through so much heartache trying to conceive a child. The few times I had a positive result it followed with disappointment. My levels were too low and the pregnancy wasn’t a viable one. Today I just received the same news. I am pregnant but again my levels are low. I have to go back to the doctor in 2 days hoping my levels double. I honestly can’t bare any more bad news and I am asking you Lord with all of my heart and soul to please grant me this miracle. Please let this bad result turn into a good one. I know Lord that nothing is impossible and I am trying my hardest to keep the faith that this will turn out positive for me. Thank you for listening.
