HELP! COULD I BE PREGNANT?

Samantha

I believe I am pregnant. I've took several pregnancy tests in the past 2 weeks & they've all read negative. But I've been feeling & seeing movement, as well as my tummy rounding out & looks as if I am really pregnant. My husband & father asked me if I was pregnant. I said no because the tests came out negative. But they keep saying it looks like I am. I have a 15 month old & I feel very similar to when I was pregnant with him. I don't know what to do anymore.
