Is this common?? My periods are always on a 26 day cycle and I'm now 7 days late. I don't feel like I normally do before a period so the more time goes by the more sure I'm pregnant. I've taken 3 pregnancy tests all with negative results. Is this normal? How common is to have negative texts this late and still be pregnant? I'm getting married next year and as much as a I want children I would like to wait.
