Can a toddler since that your pregnant?!

I’m 2dpo and for the past 2 days, after ovulation. when I go over there to see my niece the moment I walk in the door I pick her up and she hugs me for like 10 mins straight lots of cuddles and that is not like her. It usually takes some bribing to get a hug out of her lol my question is could she being sensing something? I know this might sound crazy but just a thought. She’s 2 btw and all the two years haven’t ever been this lovey towards me. I just had a chemical in December. If you had something like this happen plz COMMENT your story.
