Symptoms??? I'm not sure! HELP!!

Candace
I am about 5 days away from AF but I am having some symptoms that are new! 
I'm super constipated, and extremely bloated. My stomach has this full feeling. I have VERY prominent veins on my areola's. It started out on just one and now there are some on both. I've had some lower back pains and have been feeling super tired! I stay home so I don't have any explanation for why I feel as tired as I do!
It's been a long 15 months TTC!!
