AF showed up.. I think?

Kellie • Mother of three and currently ttc #4 due to health issues my chances are starting to shorten every day! Staying positive and wishing everyone lots of baby dust
Woke up to lots of pains and blood everywhere!! AF was officially one week late with a faint positive.. Could this be AF or a miscarriage? I'm going to watch how much I soak up a pad.. But these cramps are killing me!! I'm disappointed because I just knew this was our month! SO has a 7 year old and he really wants another baby and it seems I can't give the one thing he wants makes me feel less of a woman when I have to tell him not this month!
