TWW Metformin + Clomid

Emily
If I go by a "normal" 28 day cycle, AF is due July 25th. I usually don't ovulate and never know when to expect AF. Sometimes only once a year-or less. I'm taking Metformin and Ovasitol and had a random 3 day period on day 20 after coming off the pill (to help with PCOS, not for preventing pregnancy) so I tried Clomid this month. I went in for an ultrasound on day 16, and my doctor noticed fluid and a possible ruptured follicle, along with a triple layer lining. All huge for me! Clomid never worked for me before, so I didn't have high hopes. She also found Endometriosis, so I feel like I'm in a race against the clock. Has anyone else seen fluid and a corpus luteum mid cycle?
