Sigh

I'm very annoyed. My chart is disgusting looking all of a sudden. I went from a 98.6 temp on Saturday to 97.8 on Sunday. Today is 97.9. I'm starting to think I didn't ovulate at all, unfortunately. I'm only 8dpo, so it's too early for it to be a pre-period temp drop. But an "implantation dip" generally only lasts one day. My cervix is still totally closed and i have no CM. So I'm feeling pretty bummed and like I'm "out" this cycle. Sucks.
