Yes test again! When I conceived with my twins after 11 months of trying. I was traveling and thought I started my period but then it just disappeared on me. Then a week later the whole "bleeding" thing started yet again however it wasn't a "normal' period for me. I went and bought a test anyways thinking Oh I know it will be negative since I am on my period but this just isn't a normal period for me. I took the test and bam it was positive. It's entirely possible to get a false negative. Go and get another test to find out because you will need to get prenatal care as soon as possible. All it takes is one.........or in my case two-lol!
