So nervous

I will be 8 weeks pregnant tomorrow and have my first ultrasound and doctors appointment. I am super anxious and on edge. I have a beautiful 4 year old baby girl who is my heart and I’m beyond blessed to have her. Last year I had a loss at 13 weeks due to trisomy 13. This was an extremely difficult time and I’m still healing from the loss. After that I struggled with my cycle being irregular and I was not ovulating. I followed my doctors advice and went on the pill for 3 months back in January and to my surprise got pregnant right after finishing the 3rd pack..... anyway I’m so scared that I will receive bad news tomorrow. I know I have to think positive but last year was so painful waiting to find out what was wrong because they could see abnormalities even at my first ultrasound last time at 7 weeks. I just needed to vent and express my fears and I want to ask for prayers from any moms out there who believe in Jesus. Please keep me and this rainbow baby in your thoughts and prayers! Thanks and God bless!
