Hi we have been trying for about 4 months now, i went off the pill about 4 months ago and my cycle has been a 28 day cycle to a T. I have never went any more then a day late. Know i am 6 days late and have went out to the doctor and got blood work done that says no i am not pregnant . i have done a million home ones that all say no too. but i am never late in my cylce especcially this much and i am feeling pregnant. i am tired all the time and nasua, my lower stomach is puffy and i have cramps for like 2 weeks now. my boobs are fuller. i dont know what to do i just wish i would be able to know for sure. i get all excited then i pee on another stick and it says no. just like today i thought for sure they would say i was pregnant and they said no. is there any way that the blood test could be wrong. or is it just that i am not pregnant and there is other health issues that i should be concerned about.
