Pregnancy tests

Melissa • 26. I love my husband and so thankful for my friends & family. We're expecting our first little one.
My husband and I are TTC and we took a pregnancy test tonight and it was positive. (Hooray) My period is due today but I haven't started yet (it's my first month off the pill) But we decided to take another test to double check and it came out negative. Is it a good idea to wait a few more days to take another test?
