Has anyone had a false-negative?

I am just curious if anyone has ever had a false-negative? I am 4 days late for my period, but have taken 2 tests that have came up negative. I took the first test the day I didn't get my period and test yesterday morning. I just feel like I am pregnant because I have been peeing a lot more for the past 2 weeks, and I only pee a little bit. I am always hungry, my stomach constantly growls, even right after I eat! My lower stomach feels a little hard and I have gas a little more than usual. 
I am just curious on if there is anyone else who got negative on the pregnancy test and what they did? Like did you wait a few weeks then test at home again or did you just make a doctors appointment right away? I just feel like I need to do something as I have been ttc for the last 4 years. I had 3 miscarriages in the first two years and then I took a little break as I couldn't handle any more losses. If I am I would wanna make sure to do check ups right away just to be sure on how the progress is going. But the tests keep saying negative so I don't want to look like a fool going in and hearing I am not pregnant. 
So to sum it up, how many people have gotten false-negatives even after their period was missed?
