What do yall think?

Every thing matches up that I should be pregnant but the test. I would just be 4 weeks today. My cycle should've came nov. 26 or 28. I should be on my cycle now but I'm not an i don't feel it coming (my body gives me hints it coming) I super tired bloated peeing every 15-30 min an cramping in my uterus area. 2 test said neg. But nothing change with my body. My friend said wait a few days an take another one. What do yall think ?
