Need some advice!

So i stopped taking ALL of my meds a year or more ago because i have a wierd hard lump im my upper stomach that im pretty sure is a hernia or something along thoes lines. It isnt threatening and i cant go so far for treatment so its been unresolved.

Now that im trying to concive I want to take my metformin to help with pcos.

Anyone ever have metformin help you with pregnancy? I hear it can.
