Why is it not happening?!

Adriana
So I have a 21 year old son... I will be 39 in 2 weeks... I recently married a mighty man of God & we been TTC for 1 year... I am so sad & I feel unworthy as a woman... Could it be I became infertile in all these years?! This is my second month using OPKs. I regret not having anymore kids back in my days! Could I be to old already?
