Early signs of pregnancy before missed period.

Kat
So my period is suppose to be here around the 8th (hopefully I miss it) and I've already been feeling odd. I've been more emotional than normal and moody. I've been crying over everything which is usually me the day before my period. I've also noticed that I've been constipated (tmi) I eat extremely healthy so this has been out of the norm. I had also had some cramping during the week I was ovulating which is something I don't usually notice. I'm trying to not make stuff up in my head but I just have been feeling different lately. I'm impatiently waiting.
