Anyone ever been pregnant but can’t get a urine test to show positive?

I’m almost two months late and have tested more times than I can count..all in which we’re negative. I made an appointment for tomorrow to get a blood test and an exam to see what’s going on. I’ve heard of a few women that were indeed pregnant but urine tests just didn’t show up.

Really hoping and praying that my husband and I will be pregnant, but I’m also so nervous that it will all be negative and something will be wrong with me.. anyone experience this?

Note; my periods aren’t irregular, so I know it’s not that.
