Hello everyone I don't know why but for over a week now there's pain down below More precisely, my uterus, bladder, and fallopian tubes and ovaries It's incredibly painful, but it disappears abruptly Where should I go? I'm not pregnant I'm not experiencing menopause either My periods are regular I've been on bed rest for 11 days now And when I write at the end of it, the pain is sharp, which makes me feel like I can't get rid of the cramps What do you suggest? Should I go for an ultrasound? Or should I see a gynecologist right away? Is it worth worrying about?
