I know it seems early to be seeing symptoms. I just recently, like in the past 3 days have been getting the tenderness in the breast and the nausea. I have had a "possible pregnancy" once before and that really stressed me out before too. But nothing like this, it didn't cause anything to be late and I never had these other symptoms. Now it is possible that my hormones are out of wack. I was diagnosed during a laparoscopy in early july with endometriosis. They said that my first cycle, post-op, would be a "zinger" this would be due to my hormones getting back to normal. It has been 3 months now and I am not feeling anything like I did when I went through the "zinger" cycle. This just feels different.
It is very possible that this is infact, all in my head. A brain, whether you are aware of it or not, can make your body do things if you really want it to. I know it can't make me pregnant...But it can make me think I am.
Thank you for listening and responding, I appreciate all the info I can get.
