Cycle day 42 and still nothing 😢

Hey everyone! I guess I'll get straight to the point i have pcos. I have been trying to conceive naturally with no meds for about 2 years now. I was successful May 2015 with a BFP to 5 days later ending in a miscarriage. Since then we been trying and we have become unsuccessful. Just recently i noticed something a little off. My last menstrual cycle was from Oct.26-31 ots December and no AF. I am really hoping i am this time. I took two pregnancy tests and negative. Is it too soon idk what to do ugh ladies i need help!!!
