Trying ☹️

My husband and I have been trying to conceive for about 10 months. Not sure what I’m doing wrong. I have 2 kids from a previous relationship they are 18 and 19. My doctor said everything appears to be ok. I haven’t done any fertility testing. My period is regular. I’ve been using this app and Flo to help. It’s depressing. I’ve been taking prenatals and Myo supplements. I want to have a child with my husband. We have an awesome relationship. I didn’t with my kids father, I want to experience a “family” before I’m too old. Uggg!!! Now with this virus problem, I can’t see a doctor. I’m depressed but trying not to be. Help!!!!!!!!!!!!!!!
