I've convinced myself

Hello, it's 4am and after having insomnia = 3 hours of sleep if lucky, being nursous and slight cramping lastnight. And I got up before to do a pregnancy test and check the position of my cervix. The pregnancy test was negative but I can't feel my cervix or it's that soft I don't think I can feel it. Im still 7days away from my period. Ahhhh I'm going crazy
