What do you think

I'm currently 9dpo and have this "feeling" I'm pregnant. I don't know if it's wishful thinking or what. At 5dpo I started having heavier creamy CM. I'm exhausted easily like by 12 I just wanna sleep. May be a little early but the last 2 days I have been to my nauseated to eat anything but crackers. Today my bra is leaving marks from the tightness and very sore the last 2 days as well as some serious cramping going on. Also lower back is killing me if I stand for a long period of time. (I've worked on my feet 10 hours a day for 2 years this is the first issue). has anyone else had any of these things?
