Pcos TTC

Hello ladies, so my husband and I are 26 and have been TTC for 5 years now. I was recently unexpectedly diagnosed with pcos (sad face) so my ob gave me a script for provera and metformin. I started both at the same time, took provera for 10 days and the very next day started my cycle! So as of today I believe I am on cycle day 16! I am very anxious and nervous as my body has given me signs of ovulation (I've been doing cm checks regularly) but yet confused because I get negative opk's... we've bd'd cycle day 13 and 14 and again today... I'm praying this is it! Any advice or something that could help! This is my first regular cycle in a while! Thank you!
