Help?πŸ˜”

Katie β€’ 20 years young, first time mom to my beautiful daughter🀱🏻 Healthcare assistant πŸ’πŸ»β€β™€οΈ Type 1 Diabetic πŸ§šπŸΌβ€β™€οΈ
I've been with my partner for 9 months now, and we've been TTC for about 7 but nothing is happening?Β 
Bit of a silly question but is this normal? Or happened to anyone else? I have no known fertility problems in my family or in his.
Help would be very much appreciated!πŸ˜”
