Need Positive Words...

I'm 39, I have 3 children (20,17 &14). My new husband and I want to have a baby together (he has no children and I'm excited to start that journey with him) We were pregnant and miscarried in January. Baby would've been due August 30th. We didn't know we had miscarried until Feb 12th. I had a DNC February 15th. We have been trying to conceive ever since... no luck. My clock is ticking because of my age and I'm upset every month that I start my period. I didn't have any problems with getting pregnant or staying pregnant when I was younger. My periods are regular, I feel that my fertilization and ovulation times are correct from what the app tells me... I'm hoping this month is our month. I'm just wanting a story to show that my dreams are possible.
