How long πŸ€”πŸ€”

When y'all got prescribed metformin for irregular periods (PCOS) how long did it take for you to get your period. Tomorrow will be a week that I have started it. Also, how long did it take for you to finally conceive your blessing? Did your OBGYN have to up your dosage for it to finally take affect?? Please ladies comment down below.

Edit: I've been tracking and checking my cervical mucus. I checked my cm yesterday evening and realised that my cm had a metallic smell to it and it was white creamy, but light cm. It wasn't a strong smell at all . Normally it doesn't have an odor. Also, it didn't have brown or a hint of blood? Could this mean I'm about to start my period finally.
