Can your mind trick your body into having all the symptoms of conception/very early pregnancy? I am only 4DPO and have the worst gas! All day long. I have been cramping for several days and my boobs are sore but just on the sides by my armpits. Also, I tried to put on a pair of jeans and could barely button them because I feel so bloated. Also I'm starting to get a more jelly/creamy stretchy looking CM. Is our mind powerful enough to create all of these symptoms?  I didn't think symptoms started this early...no nausea, not feeling tired aside from long days and getting up early for work. Just curious:) Hoping my mind isn't playing tricks on me!
