Need help!

So I used to be on the patch for like a year and a half and I switch over to the pill because the patch was starting to fall off and it just wasn't right for me. For two years off and on I have had bad abnormal discharge, plenty of time I went to the doctor and they said it was either B.V or yeast infection or UTI, well recent I started the pill and I mean I had the sickness the first day  but other than that I had no problems. I had gotten my period the 18th and started my pill the Sunday like the gyno had said. Well I started to get discharge again and it was a yellowish discharge that filled up a panty liner. Within a couple of days I started to have blood. So I was in the shower and the doctor told me to do the douche with apple cider vinegar and use monostate but when I went to clean it out like the douching I felt this weird ball like thing and I immediately started bleeding . I am terrified and I have no clue if It's supposed to be there or what 😓 someone help me please!
