Pregnant or not, that is the question!

Officially 10 days late, haven't been this late since my early 20s and that was due to depression. Keep getting cramps on and off, same for sore breast (if they get squeezed or any pressure they hurt more), constipation (tmi sorry), sleeping way more than usual, and some serious mood swings (ranging from wanting to cry to, ill cut you!!).Pretty much all signs of pregnancy but still bfn! Haven't taken one today and I believe that would put me at 5 weeks.

Why are the female bodies so complicated?! What do you ladies think?
