Cramps after period is over

An

So I have suspected PCOS, currently getting a million and one tests done. I had this super weird period where it was heavy for 2 days and that was it. I usually bleed for 4-5 days and it goes mild-heavy-light. I did see the doctor and she just said she thinks it might be PCOS with my family history of it and my other symptoms. Anyway, my main question is what do you do when your cramps just don't stop? Its really starting to annoy me and I'm sick of being emotional all the time. Its been almost 2 weeks since my period
