4 days late


Ok here’s the thing. I got my tubes tied June 2017 after my 4th baby. I was supposed to start my period but now going on 4 days late. I started cramping 6 days ago. Figured I was ramping up to start. Still nothing! I know tubal isn’t 100% effective as nothing is but I can’t be right? I took a cheap test the day after my period was supposed to start and it was negative. I am still cramping where I’m constantly going to the bathroom to check and it’s just extra vaginal fluids (sorry TMI). Please tell me I’m crazy and I can’t be pregnant!?!?
