Questions???

Ok so I'm not two days late and my period has always been on time, I took a hpt and both were BFN.. but still no signs of AF at all, but I've noticed signs of pregnancy. I'm so confused, could I possibly not have enough hormones? How many woman have had to go to the doctors for a test because hpt didn't work? I'm hoping that tomorrow morning I get a BFP. Hubby is nervous and doesn't want to talk about it in case of jinxing it. Idk what to do ugh!
