Okay so I haven't gotten my period since feb 27th I'm usually a 3 day so it finish march 3 I'm reg never missed or have my period go crazy always had it on time maybe 2-3 days but not a week and one day which I am currently. I went to the hospital due to not feeling good so they did what they have to take my blood test and pee etc , was I there for hours 🙃🙃 , anyways results came back he said I wasn't and asked me if this the first time it happened I said yes he wants me to keep testing because there's a chance my hcg level was to low I have to wait other two weeks but I'm just like its weird I thought since I need the blood test it would show up positive guess not .. 
But question is has anyone went through the same thing and did become pregnant??
