I am 27 yrs old my tubes we're tied last year in Feb and my periods have always been regular since I can remember even after having my three kids that I ve had all natural. Recently I haven't had a period since April 18th and I am now 11 days late I have taken two home pregnancy test both negative. I also taken one urine test at the hospital and a blood test at the hospital also negative. I still haven't got a period yet and there is only now one day remaining in May I would like to know what's going on? I know that the only time I miss a period is when I'm pregnant but the hospital didn't seem to think so I am worried because my tubes are tied and I don't know if it's a ectopic pregnancy or not.
