So I was supposed to start my period on September 24 and I still have not gotten it. The first few days I was nauseous but no other symptoms. I took a pregnancy test then but negative. That last few days I have been spotting abnormally then when I start my period. It’s been very very light. I am going to ale another pregnancy test tomorrow. My question is could I have implanted recently and that’s why the other test came up negative. My cycle is 25 days and I have never been late so I am wondering what’s going on, if I am not pregnant. Any advice or thoughts?
