Two week wait

Brittany • Mommy of ✌🏼boys!
I'm in the TWW stage of my first month TTC and was wondering if anyone "knew" they were pregnant within the first week. I'm about 5 dpo and have a weird feeling in my gut, not sure if that's just nerves of hoping I am pregnant or if it's something real. Has this happened to you and were you right or wrong?
