Did you know you were pregnant before a positive test?

I swear I’m losing my mind. We took a break from trying this month so no clue about ovulation and I’m still like 6 days away from my period but I feel nauseous and am peeing more frequently like middle of the night which hasn’t happened since I was pregnant with my first baby. We are wanting a second. But I always roll my eyes when people say they have symptoms this early and I know most likely it’s nothing but idk lol curious if anyone else experienced something similar?
