I just started Metformin last month, and will be starting clomid with it this month once I actually start my period.

However, I am currently four days late. I took a HPT and got a BFN. I’m having all my period symptoms except cramping.

The only thing that has changed for me was the Metformin. So I am thinking it is the cause. Has anyone had it make your cycles longer just by itself??

We have been TTC for almost two years so the BFN is really disappointing.
