A chemical pregnancy! Why do they have to say that?

Deb

Last week I had 2 positive tests, I was excited and scared at the same time, but yesterday afternoon I started bleeding and cramping, this little bean hasn’t stuck and I’m gutted.. I had an awful feeling it was going to happen again.. because I was only 4w 4d they call it a chemical pregnancy, I really hate that term they use.. to me it’s a miscarriage, I conceived, it implanted enough to give off the hormones for positive tests.. what have I done so wrong, this is the second miscarriage I have had with my husband,🙁
