What Causes Sharp Pain In The Pelvis?

Hi, my name is Jackie, I am 19 years old and live in the USA. I just went to the ER because I had sharp, and severe pelvic pain. They tested my urine and did an ultrasound and found out that I was A) not pregnant, and B) had a small cyst on my left ovary. They gave me an anti-inflammatory and tramadol for the pain but the pain is not going away and I m gaining more symptoms. I now have really aggressive and pounding headaches, which hurt the most at the bottom of the back of my actual head and top of my neck. I also started bleeding, almost like a period. Which was only strange to me because I have had an IUD (Mirena) since I was 16, and have not had any sort of bleeding from my vagina since a couple months after I had it inserted. I don t know where exactly to go next, my work makes it hard to spend too much time in a doctor s office. Let me know what any of you think, thanks. -Jackie
