Help ease my mind!

Kaitlyn

okay so AF was due yesterday, no sign of her yet, which is weird for me because im always on time like clockwork. Yesterday I got a blood test and the result was hcg 2.39 when normally im at zero. ive gotten 2 faint positives at home and then 2 negatives. My bbt usually drops at 10dpo and it has yet to drop, its actually rising! what in the world is going on? my boobs are killing me, which again is weird.. help?

first test:

second:

and then my negative..
