Advice for ttc with pcos and emotions

My partner and I have been ttc for 4 months with no luck so far. I have pcos but my gynecologist had said I should be able to conceive on my own but if I was trying for 3 to 6 months with no results I should go in. I will be scheduling an appointment soon. But every month that I get my period I get sad and start pushing my partner away. I start shutting everyone out. I’ve spoken to my partner about how I feel when I see others with kids and I am struggling. I just want to lock away. His response was “it will happen when it’s supposed to”. I totally agree. However knowing it will happen when it should doesn’t help me much. Another issue is my gynecologist had said we should be having sex at least 3 times per week. Most times we would have sex like 2 times per week or 2 times every other week. This is because we don’t live together. We have been looking somewhere to live together. But even that gets me frustrated especially since I will be 30 soon. Any advice on how I can get through this time. I am an emotional wreck at the moment.
