Hi Shin! Thank you for being honest on what you are feeling on the current situation that you are in.
I felt that and just to share my wife has been in the same situation that you are in. She had PCOS too and somehow, we are in the point of giving up. We praise God that and to share we now have a 4 month old daughter.
Here are stuff that we did / changed not sure if it will help but who knows.
We discuss our burden with some of our closest friends. In that way, we know that we have some support on prayers and battles.
We did lose weight, we cut down our food intake weight per se but focus on the nutritious foods available.
Always check and monitor the fertility day. We do it when it is high, and we do not if it already pass the fertility period. Also, both you and your partner should rest. Sometimes it is also the condition of the partner, his sperm count etc. that affects the fertility.
Take folic acid - and have a trustworthy OB (ung magaan sa loob mo at feels mo na maalagaan ka)
Not sure if it helped as there's no therapeutic claims but both of us took iFern products the 3 bottles as supplements.
Praying that you have your own in time!
