Thank you for the query.
They keep asking you about sexual activity probably because such symptoms can be caused by ectopic pregnancy.
It would be much easier to help you if you attached performed tests.
Your symptoms can be caused by urinary tract infection
or stones, diverticulitis
, uterus inflammation, ovarian inflammation
With urinary tract infection or stones you can have frequent urinating, burning when urinating, back pain or groin pain.
Diverticulitis is associated with severe constipations. Blood in stool
or mucus in stool can be present.
I suggest you to have abdominal ultrasound, full blood work, urine analysis. If blood in stool is present, colonoscopy
should be performed.
Hope this will help.
