Possibly pregnant?

Whitney • Mommy to Antonio Wife to Juan ❤💍

I haven't had a period since November 4-8th. I was supoossed to start my period again on the 10th of Decmeber and have had no sign of it. I have tested negative several times, but for the past two weeks have been seeing movements in my belly, and have had my husband and family see them too. Is there a way I could be pregnant and it not be showing up on the tests? TIA
