I Am 5 Days Away From My Period Starting And

I am 5 days away from my period starting and I took a digital pregnancy test today after sleeping for 3 hours. It came out postive! My husband and I are so excited! Although we know it's early. I went to buy another test to be sure after only waiting an hour and a half from the last one not allowing my HCG levels to rise again. It came out negative. I'm going to test again in the morning with first morning urine. Do you think I can be pregnant and the 2nd test was a false negative due to not waiting long enough in between urinating?
