Salutations Ladies,
I've taken ovulation test every day for 13 days and haven't ovulated yet.... I use the Clear Blue Digital Monitor System. 
Also this cycle has been a very very long cycle. My normal period is between 28-30 and this one is showing  37days?? I'm so confused. 
Back history TTC:  MC April 2014, August 2016 was told I have mild PCOS started Clomid 50mg for three cycles all failed. Jan 2017 OBGYN upped to 100mg I'll be starting them in March 2017. 
Thoughts????
Update: tested from day 8 of cycle to, today 22 of my cycle and just got a "high"ovulation on my Digital  Monitor. 
My cycle is so messed up!! Ugh.. I'll keep everything posted.
