Hi, my name is Anna and I am 23 years old. I was supposed to get my period around April 23rd. I never got it, but last wed I started spotting. It started very very light and only when I wiped. Today I still have spotting but it is a little more then before and a little darker. I took 2 pregnant tests this morning ,and they both came up negative. Is this something serious or can It be false negative tests?
