Nervous & excited for tomorrow

Tomorrow I will be 12w2d pregnant with my rainbow baby. Tomorrow is also my 2nd ultrasound appt. Since my first pregnancy ended in MMC obviously i am very nervous. (Feb 2015 i went for an 11week ultrasound and found that baby stopped growing at 7 weeks) I already had 1 ultrasound at 8w3d and baby was perfect, and even moved around. Heartrate was 174. I just cant shake this nervous feeling and anxiety, the fear is in the back of my head. I know all this is normal to feel but i want to be happy and excited, gr. Please keep me in your prayers that all is well tomorrow 🌈❤
