My heart is heavy

My heart is heavy, I feel like Hannah in the Bible, on my knees praying to the Lord God for a baby and trying to be patient and content in the meantime. I am finding it especially hard this week, 2 of my closest friends have announced their pregnancies this year, I am super happy for them, however I can't help but feel sad too. My husband and I have been trying for 1 1/2 years (3 months then a break, then 15 months consecutively). In a week we find out the results of the blood tests/ultrasound that the fertility specialist has sent us for. The wait is hard.
