Confused and need help

Lexi

So im on CD 58. I dont start my period unless i take provera for 10 days but it gives me the worst symptoms such as super moody and emotionally unstable , i cant even function at work on it. I took it only one pill on the 15th (10mg) and couldnt take the symptoms so stopped. Today i am cramping and had a little bit of blood when i wiped. Today is 7 days after the 1 pill i took.

Do you think it could possibly just be the provera even just with 1 pill that is making me bleed? Or implantation bleeding??

Please give me advice!! Oh and i have PCOS.
