How do I know if my metformin tablets are working.

[kristina281192]

I've been on metformin tablets for nearly to weeks now and the doctor give them me as I have high blood sugar which if it spike more I'll begin the start of diabetes but I also have pcos cysts have disappeared but I have unwanted hair and also irregular periods I last had a period on the 31/03/16 and haven't bleed since due to me not ovalating , currently the doctors are taking blood every weeks to check for ovalation but currently nothing before April I had a period in December, January, February, march. So I'm litylw frustrated as me and my partner are currently trying for a baby. Since I've been taking the metformin tablets I've been feeling much more energetic, much full faster and feel as though my stomach is lighter but can tell as most of my body fat is on my stomach and just my stomach.

Can anybody shed light on my situation.
