A little confused 🤨

So the app says that I ovulate today I woke up feeling nauseous which ISN’T normal for me and I suspect that I ovulated on the 15th because CM was different and I had sore nipples which IS normal but I’m seeing that nausea can be an ovulation symptom.. now idk when I ovulated but I know it is way too soon for pregnancy symptoms but due to my obsession with google searches I also read that some people have experienced things as early as 3dpo 🤦🏽‍♀️

(I didn’t have opks since I wasn’t actively trying but we weren’t preventing either😬)
