11 days late

Pa

I’m 11 days late! I’m always regular an 28 day cycle.

The only time Ive been late was three years ago when I got pregnant with my twins.

I took a pregnancy test last Wednesday and it was negative, however it’s Tuesday now and still NO period.

I have frequent urination, nausea and occasional breast tenderness.

Do you ladies think I could really be pregnant? Should I test again?
