How I found I was pregnant with baby#2

Been super super tired, been eating stuff I don't & wouldn't usually eat & then I had this TERRIBLE BACK pain that wouldn't ( still hasn't ) gone away... So I figured why not take a test for heck of it me knowing I'm very cautious when I have sex because after having my daughter BC was making me very sick. I tried the shot & the implant in the arm.. I told the father right away & he's happy
