I had unprotected sex but he pulled out. I got my period a day later, but my periods are usually really heavy and last around 6 to 7 days. It was onlt heavy-ish 1 day then i spotted for about a week. And ive noticed thay my hair leg hair and my arm pit hair grow back faster than normal. And also ive lost my appetite, im not as hungry as i usually am. Do you think i could be pregnant?
