Long period

Hi ladies..I've always had irregular periods...sometimes it would be months before i get my period..

On 5th August i started taking metformin and AF arrive on 11th ..but i had side effects..diarrhea was the worst ..and didn't stop bleeding until i stopped taking the pill(recommended by the nurse)..my period was 13days long..

No period in september and got my period now out of no where..

the app says i ovulated .. but i did check for ovulation for 20days after my period..all negative

10th day today still bleeding...is this normal?

Do any of you have the same issue..
