Ttc no opk.

Katie
So after 5mc I've decided to not do opks, or test untill my expected  period. To much money wasted. Anyone get pg using the green fertile window only? And no idk what it is except for the Prozac. Ad I've stoped takjng it with doc approval. And my uterus is good and thick already so he said I can ttc asap. Lol so any advice?
