Yesterday, I went to the emergency room because I was having really bad cramps and I'd been nauseous for over 12 hours straight. They did a urine test, vaginal swab, took blood, and gave me an X-ray; after all of this & about 4 hours in the ER room, they told me it was constipation. I've been having back, stomach, and pelvic cramps since March & my periods have been kinda messed up. Could they have missed the Endo if I have it? I'm just looking for answers, thank you.
