1-2 weeks pregnant. But am I actually pregnant?

Kari • Hi! Kari's the name. Preggo with my second bundle of joy! Love muffin #1 was born March ‘17. 👶🏻
I tested two days ago and I got all positive tests!  I also took another pregnancy test telling me that I was 1-2 weeks.  I've started reading the baby books and I'm learning that "conception" hasn't occurred yet?   I just can't understand where I'm at.  Ovulation was two weeks ago, we bedded exactly two weeks ago today.   I tested two days ago with the 1-2 week result.   This means I must be exactly two weeks pregnant, right?   Am I in fact pregnant?  Shall I wait another two weeks to tell anyone?   So confused.    I'd love for someone to help me with this and explain a bit more in layman a terms.   Am I pregnant?  Where am I within the pregnancy?   I believe my period is due tomorrow..  Should I be worried and possibly expect its arrival?   Appreciate any help!!  Thanks! -Kari
