HELP!! Vvvfl. AF almost a week late!

Karen • TTC!!! If it happens, it will be my first!!!

Had a MC in April at 2 1/2months. Haven't tried to get pregnant (just hoping I will) I haven't been feeling good, nauseous, exhausted, loss of appetite. And now I'm a week late on my period!!! Just trying to confirm this (since I heard a lot of negative things about CB test). I just want to know so I can take care of myself and have a successful BABY!!!!!
