late period

Megan
Anyone ever have a positive pregnancy test 2 days after a negative? My period is late.. like 4/5 days late.. my cycle is usually 29-34 days and if AF doesn't come tomorrow it will be day 39 for me.. I took a test Saturday (5/27) at like 7pm and it looked pretty negative to me. I have a three year old and have taken plenty of tests. But wondering if I should try to take one tomorrow morning? Or anxiously wait another day. We've been trying for baby #2 for almost 2 years now so I'm hoping this is it.. just looking for some insight on BFN tests before you BFP tests. Thanks ladies.
