Cervical mucus. Asking in here so hopefully I can get some answers

Leah • Happily married😍 27 years old I’m losing weight. Have a fur baby and going to start ttc our rainbow late April:

Could lots of cm be a good sign? I haven’t ovulated yet and it isn’t fertile mucus yet but I’m usually dry on cycle day 12 since I usually don’t ovulate till cycle day 17. Took letrozole 3.5 mg for days 5-10. Also on 1,000mg of metformin have been for a year.
