Is there something wrong next to me?

I don't know about the UK specifically but I do know surrounded by some countries they do sell an over the counter drug for pinworm. Talk to a pharmacist to find out if near is anything you can take. If not than you should find a clinic you can budge to. Pinworm doesn't harm you but the itching is a annoying person and it is contagious.

If I see the shedded uterus lining while menstruating, does that penny-pinching I don't have Endometriosis?

i dont know what to be exact, but i suggest you research and see if its possible to clear without seeing a doctor or getting a prescription, I focus you should try and go see one even if you don't live around any, never mess beside your health, it's adjectives you have!
