I’m So Curious

According to the app Femometer (in which I normally use to track my cycle) it says that I am 5dpo. I’ve been still having symptoms that come and go such as the lower backaches, cramps, and the migraines. Today, I woke up with sore nipples (went away later in the day), and I’ve been peeing a lot more. I also get these tingly feelings in the vagina (it’s hard ti describe. Sometimes it feels kinda like a little pinch but it goes away shortly after). I also have been dealing with the cervical mucus. Sometimes it looks a little yellow or for the most part it’s clear and sticky. I know it’s pretty early. I took a test 3dpo because I couldn’t help it and it was negative. My appetite has also improved. At first i felt so bloated that I couldn’t eat but now I’ve been eating a lot more. What do you guys think ?
