My last period ended dec.14, I'm usually regular. But I have yet had a period. I 'feel' as if I'm pregnant, but all the tests say NO! But when I take an ovulation test it says I'm high fertility?! That's how I found out I was pregnant before by an ovulation test...but this is dumbfounding me. On the period predictor I've missed three times when I'm supposed to start. I'm up todate at the doc. So nothing is wrong. What else could it be? Please help
