Ovulation medicine ?

How long have some of you ladies been ttc before your doctor put you on medicine to help you conceive better? Had a miscarriage in 2020 and then it took awhile for me to even conceive my babe I had in 2021. And now this time around I’ve having trouble even trying to conceive again but worse I had one shot just one freaking shot of depo in November of 2021. And I’ve been having periods every month I do ovulation tests that have looked positive but not entirely sure if I even ovulate or not. I have an appointment today with the obgyn to go over and discuss everything. I’m just curious to the question above with the girls that has been through this.
