Dawn
Okay, so last month my period was 2 weeks late and then when it did show up it was very dark (very unusual for me) it lasted a few days and then went away, this month I'm 3 days late and have all the early symptoms of being pregnant. I've taken 2 HPTs and both came back negative, but I feel different if that makes sense. Has anyone else had this happen and been pregnant? Thanks!
