off birth control, Wellbutrin and Prozac

I went off my minastrin 24 Fe birth control on 12/3. This birth control caused typically skipped periods each month or a very short and light period of 1.5-2 days per month. I had a very light period 12/2-12/3 this past month. My obgyn said that skipping periods to very light and short periods is normal for this birth control...
My husband and I are TTC. I've seen my obgyn and psychiatrist who said I should go off anti depressants, assuming I'm okay without them. I really just took them for some anxiety and very mild depression. I stopped taking wellbutrin and Prozac. 
Anyway, af was due a couple days ago and I still haven't gotten period. Has anyone taken these medications and had a delay in period returning after stopping anti depressants? 
Thanks in advance everyone.
