Testing too early!

So, I have different ovulation apps and Ovia is telling me test in 2 days and glow told me to test yesterday and ovulationcalender.com told me to test today. All have been negative but I believe I experienced implantation blood yesterday evening, I checked my bbt this morning and it was 98.8 and I just rechecked it just for the hell of it and it read 99.2! I'm just confused because they all have the same information in it. I just don't know! I'm getting so discouraged. Sorry, a lil rant.
