I never missed a period either except once in my life it didn't come for a month and did a blood test to confirm pregnancy and I wasn't pregnant.Now with my 3/4 babies I tested and tested I knew I was but they didn't want it to be known I guess, they were living inside me till finally I get a positve it was about 4-5 days passed period.Wait and retest in a day or 2 with first morning urine try really hard not to pee in the middle of the night so for it is concentrated
