I am 32 years old and have my tubes tied for 3 years now and for some reason a couple of weeks ago I have noticing some changes like my breast hurting, cause, specific food cravings, mood swings (very emotional) and I have egg white discharge that has been coming out and mild cramping and just tired all the time and dizzy could I be pregnant. I am due on my period any day and I have already taken a pregnancy test that came out negative. Am I going crazy what is going on with my body. I feel like I am pregnant. Any thoughts?
