A little confused

Kiara
I started my period on monday. It lasted through yesterday which was thursday. Slept with a pad on all night had no bleeding. Today I had no bleeding. Around 8 tonight I felt wet down there so I ran to the bathroom and it was fresh blood in my underwear and it was accompanied by sharp pains in what felt like my right ovary. Anyone had this? I do have pelvic congestion syndrome and had a few cysts on my ovaries...
