metformin & a late period

alice 💕

I’m on week 2 of taking metformin and my period in now 22 days late!

Does metformin effect your periods starting?

I am usually every 35-40 days!

I have all the symptoms of my usual period but no period!

Any ideas?!

I also did a pregnancy test when I was 12 days late and it was negative.

Many thanks x
