What shall I do for heavy periods and anemia?

Hi doctor,

I am 24 years old. I have had irregular and painful periods since I started my first periods in 13. I have a kid, who is 3 now. It was a normal vaginal delivery and I did have a fibroid that came out later that day. But as of lately, I have been having a very pink tinted discharge with pain and uncomfortable. My last menstruation was very heavy and painful. I got up from bed to go restroom to change and my thighs were trickling with blood. I felt horrible with painful lower back pain, nausea and I almost threw up from it. I got in the shower hoping to feel better, but as soon as I got in, it felt like someone flipped my switch off. My arms and neck went limp and everything started to go white. My mother helped me to lie down in bed. Then, I felt cold, clammy and shivering. I took two Tylenol to help the pain, which it did. I went to the doctor that day and she just drew my blood and said I was anemic and not pregnant. I followed up with a gynecologist, he said it could be endometriosis and everything else is fine. He also told me that I have high risk HPV. I have had a transvaginal ultrasound that showed everything pretty much fine except for the follicles on my ovaries. I am so confused about my health condition. Please help.
