Keep getting negative test!

Me and my husband have been TTC for about 3 months now. We've gotten the Ovulation kits and as well as this app Glow. it said I was ovulating on thanksgiving we did our deed. Last week I had what I thought was implantation bleeding. My expected period was suppose to start today and I haven't had any signs of AF coming and I keep testing and having negative test. I have signs of pregnancy last night I cried for 30 mins because hubby wouldn't cuddle with me! I don't know what to do we want this so badly after we had our still born! I've just given up!
