My period is not suppose to be here until the 16th of January and it came 5 days early only it was very ligh ink with mucus. Then it stopped the same day then the next morning I jumped up to pee and it was still not here. Then later on it was here it was light red and only seen when I urinated. Then it stopped again and now its on when I urinate again. I have had unprotected sex and could be pregnant. But why would I bleed? Also painful when I move its like cramps but muscle pain what's wrong with me and what should I do?

It maybe a Urinary Tract Infection
