So Confused

Okay Two weeks ago I had went to the doctors to get blood work done I did have uti  but other then everything came normal negative pregnancy test  So anywho  Monday night I start getting the pain in my left ovary so I went to the hospital and they did a ultrasound and a vaginal ultrasound aswell  they said everything was fine nothing wrong with my ovary. I started my period on Wednesday well technically I was spotting so now the only time I see blood is when I wipe myself  keep in mind this is so un normal because when I start my period I make a river of blood sorry tmi and I have lately been feeling sleepy  help should get a pregnancy test
