Sex drive gone after fertile window?

Okay so my sex drive is always there, it only disappears when I'm sick, like really sick. This cycle my husband and I decided to TTC before he leaves for his station in Japan. My body is doing a lot of unusual things now that my fertile window is over. my question is whether or not I'm going crazy or just overwhelmed with wishful thinking? This month I never got the egg white cm like usual and only started getting watery cm after we started having sex. I've also not had any breast pain but holy crap have my nipples been itching and that never happens either. I've also been low-key nauseous all the time but not to the point of actually throwing up. I'm only about 5dpo so I'm sure it's too early for signs and definitely too early to test. starting between 3 and 4dpo, my sex drive just disappeared entirely and that's the weirdest part. Am I being crazy or are these differences actually good signs that maybe I will be pregnant?? These trends don't match at all what my body usually does when I start having sex after long periods

without.
