I've been on 1500mg of metformin for about 3 months and I still haven't regulated. I'm really getting discouraged too.
Since starting met, I had a ~90 cycle and then induced my period with provera. I'm now on day 18 of my cycle and I'm pretty sure I haven't ovulated and haven't seen a temperature shift yet. I guess I have to keep my fingers crossed for my next cycle.
