Looking for help!

I ended provera on Wednesday, I bleed on Thursday with severe cramps and very light bleeding on Friday. if this constitutes my period I should start Clomid today (day 3). I typically do have very light period, Which is why I took Provera to begin with but I am not sure if I should count Thursday and Friday as my period or if I would be getting it again later (since many people describe having very heavy period with provera). I am nervous to wait and see because that means I missed another month of i don’t bleed again- is there anything negative that would happen if I do take Clomid today and that wasn’t my period? Any advice welcomed!!!
