Praying for Successful Fertility Treatments

Dear Lord, We’ve been married since 2008 and have been trying for a child this entire year. My husband and I are undergoing fertility treatments but they have so many side effects (physically) for me. The money we are paying for these treatments is amazing and causing me, much stress although my husband is always willing to pay. At times I do not know what to do and feel my faith is so weak. Please help us, if we should see another doctor, just try without fertility treatments. Please intercede and guide us.
