SOS PERIOD NO SHOW

So i’m 2 months PP... i bled for a month when my baby was born and then it stopped. A few days later i started bleeding again which i assumed was my period. Counting THAT as my period I’m already 10 days late and had a few oops with hubby... I’m worried about being pregnant. I took a HPT like 5 days ago and came negative... I have been feeling cramping but nothing yet

Anyone has gone thru something like this?
