Trying to conceive

Rachael

So I have been trying to conceive on and off, to cut a long story short when I was with my ex of 5 and a half years we were trying for over 1 year but I did not manage to get pregnant as I was diagnosed with PCOS, I am now seeing someone new we haven't been together as long but we would like to start trying soon. I know I should try longer with my new guy but I don't know how long I should wait for until I seek medical help.

(We have been trying for 3 months)

I don't want to go to my doctor for him to say wait again for so many months as that's what he said last time.

Advice please
