Positive after missed Period?

So I took 2 tests last Thursday and they both had a vvfl. Of course I got excited! The next morning I had a doctors appointment for a pap and they did the routine pregnancy test and it came back negative. I am now 3 days late on my period but still keep getting negatives. Has anyone had this happen to them and was actually pregnant? Honestly just feeling so bummed right now! 😞
