Early symptoms?

Hey everyone -- just wanted to see what you all thought since it is too early for me to take an hpt. Using OPK's I got my first positive last monday 7/7, and bd'ed that night and the next morning. Had some ovulation cramping the next few days. Now I'm getting headaches, hot flashes, low grade fever today -- 99.1, creamy cm, extremely tired, and sore . But my s don't hurt just sitting here. They are sore to the touch... under and in between -- i think they feel like bruised when you push on them. Also noticed today they were sore going down the steps. The only other things I've noticed which can be due to several other reasons are sleep disturbances, lack of motivation lol to do anythinggg. i just wanna lay around all day, and some gas? lol. Does this sound like early pregnancy to you?
