Af due dec2 still nothing!

Hannah • Single mom
I'm hopeful for a baby but it's been three years of trying and nothing to show. Im never late and now I'm 5 days late no cramps or anything to indicate im close to starting but I took two tests tonight I barely had to pee but forced it and they were both negative I know it's best for morning urine but I got excited and thought surely it would show up if I am pregnant. But is there any read why I could be late?
