Help please!! I need replies!

So recently I have missed my period, and I have ruled out pregnancy, because I have taken two tests and even waiting 3 weeks after my missed period to take the test. I have been extremely stressed lately about starting my period up until taking the pregnancy testwhich reassured me that I’m not pregnant... my periods have been kind of wonky here lately.. I had a month when I had two periods in less than a month which was odd for me. But I was looking online at some supplements that I could possibly take to somewhat induce my period or at least get my cycle back in track and I found Femaprin... never heard of it before, but I was wondering if this would be a feasible option for someone who is NOT interested but in becoming pregnant, only to start my period soon and get my cycle back on track.
