My niece has been experiencing several unusual symptoms over the last month and is in incredible pain. She can't seem to get any answers. Last month her period was 2 weeks late, after that she started experiencing intense pain in her abdomen, left side and back. She says it feels like she is having contractions. She has also gained 15 pounds in a month and has blood in her stool. She's 23 years old, is not pregnant, has had pelvic ultrasound, stomach/abdominal x-rays, bloodwork and everything is coming back negative. Last year she was told that she had an abnormal pap and tested positive for HPV. She is terrified and not sure what to do. Doctor told her to go for a colonoscopy, but she can't get an appt. for a month. Any advice?
