Feeling down

Terra • Married to my Mr. Right. Mom to my IVF heart warrior daughter born November 16, 2017.
I did my first round of clomid this month 50 mgs and am on cd 21 I used opks this month basically from cd 9 when I took my last pill to today and never got a positive my gyno told me the most important days were 16, 18 and 20 make sure we had sex then and we did but I don't think I even ovulated :( guess I wait now to find out if af shows up or not. This is so frustrating I was so hopeful clomid would work and help me ovulate and I just don't think it did totally feeling bummed out right now ☹️
