A little advice

So i have pcos and after 2 trying everything in the book. Im finally giving birth control a try for a few months. I strongly believe this is what helped me with my first child but that was with my previous relationship. My husband now has low testosterone and low sperm count so his doctor said it has alot to do with his thyroid issue so he increased his medication, he is giving him testosterone medication and said its a 3month process and it will increase his sperm count. My question is have any of you ladies ever been on these pills and then gotten pregnant. Please let me know also has your hubby had these issues and had good outcome . Thank you
