Early pregnancy signs

Hi all, unsure if this is where I'm supposed to post this but I'll remove if it's in the incorrect category. please let me know where I should post it.

I've been pregnant twice now and both times I didn't know till I was past 10 weeks! I keep seeing people catching on to pregnancy around 1 - 2 weeks. Am I just stupid?! why can't I pick it up sooner?! I don't understand 😔
