Discharge

can someone please help me. I've been to the doctor and was diagnosed with pcos 4 months ago started metformin right away. Dr. said I wasn't ovulating but the metformin might make me ovulate. I've been having discharge that was white and stretchy all week. well today when I went to use the bathroom and wipe it was white with blood in it. I don't start my period until 2 weeks.

Thanks for the help!!
