Please help! Give me words of encouragement!!

🌸🌸🌸
My progesterone last week was 14.87 and today it is 13.71. I am 4w4d. My hcg was 184 at 13dpo and then 446 at 15dpo.  My ob is putting me on progesterone medication nightly.  Please please share some of your similar stories and tell me it's going to be ok!! 😭 I'm freaking out. I don't want to lose this pregnancy!
