Early pregnancy symptoms?

Okay so I have the Ovia fertility app and last week was my most fertile and when I ovulated. It's been a few days and I've been feeling light headed, nauseous, and just overall weird. Could it be possible that they are early pregnancy symptoms?

Oh and also it's like I have pressure in my vagina and that happened at the beginning of my other two pregnancies.
