Anyone ever been pregnant but get negative pregnancy tests? I was due my period 7 days ago. Did a pregnancy test 3 days after and again at 6 days. Both negative. I constantly feel nauseous, dizzy and tired. I had some cramps when I was due but nothing since. Went to see my GP today who advised I repeat a test on day 14 and if this is negative, they will send me for a blood test if i am still having the same symptoms. Anyone had similar experiences?
