Period WONT start 😓

Keisha

So I have PCOS;however, I take metformin daily for it and my periods have been somewhat normal for the past year. This cycle, I am currently 18 days late. NOT PREGNANT. I feel miserable, like I “need to have my period”. Any ideas on how I could make it start? I feel like my body is trying but just can’t get it to happen. My back has been aching, breasts hurt, bloated....but no aunt flow.
