TTC 1+yrs natural...

Shay • 24 ♡ Wife ♡ Momma Bear x3 & expecting #4 June 2020
Has anyone been able to conceive "naturally"? By that I mean, without doctors help? 
My DF and I have been BD all natural (no protection) for 1yr 6mth. I am going to buy all my vitamins, his vitamins, OPK's, and some other things. I have never been to a doctor though.
