38 years old, new and totally freaking out!

I recently started on this app and group. I am 38 years old and been ttc for 4 months now. This will be my first child. My husband has a 16 year old and is 39 years old. I was always told by my Doctor and everyone not worry about our ages. I am health, my husband is healthy and I have a very regular cycle (on and off BC). I have learned a lot so far to help us ttc but I am also freaking out more after reading all the posts. My anxiety about ttc since joining this app is out of the roof now! It's all I think about! I feel sick to my stomach. 😦
