Anxious!!! 2 more days ahhhhh give me some encouragement come off depo 8 months ago?

I came off the depo shot in November and in March of this year I started getting my periods ago back to normal. For the last 3 months I've had my periods like clockwork and I'm due to start in 2 days but I'm praying for a BFP!! Lets hope this is my month!! I've taken a few HPTs and 2 of them had faint lines but I think they were evap lines so I've brushed them off as a failed test. Today I took a ClearBlue Digital and it said "not pregnant" but I took it at night and not my FMU and I chugged a bottle of soda before I took the test so I dunno if it was acurate enough to be a BFN or if I messed up the test by taking it at night and diluting the test form drinking soda before the test. My period last month was on the 16th so I'm about 2-4 days before my period is due.. Ive been having a little stomach pain tonight so I'm hoping it s my body getting ready and not my darn period! lol Im just wondering if I'm testing to early.
