Pregnant?

So I had my period on time but still feel pregnant and I’m bloated, exhausted, cramps in my uterus, headaches, etc. But I’ve had negative results even today and I’m a very skinny girl that doesn’t bloat until my period comes. I was just wondering if anyone had stories of not knowing and still had your period, and was getting negative results. I know I’m not pregnant because I’ve had my period and the test are negative. But have you? I’d love to hear??!
