Pregnancy symptoms? But negative tests

Celine

Hi,

My period is 3 days late and all the tests show negative. Have been trying for 9 months and it is not uncommon that my period is irregular some months.

Have been nauseas for 5 days now, hungry but lost of appetite, burping alot, extremely tired (sleeping more than I usually do).

Had some cramping yesterday.

Have anyone had similar symptoms and have received positive result after a few days?
