Can't tell if my mind is playing tricks on me or I'm actually having symtoms. My period isn't scheduled to be due for another 12 days but since the 7th, I've been having nausea, tender boob, and lots of head aches. I can't eat anything! I have constipation and had back pain and cramps but they went away. Anyone have similar Symtoms?? This will be my rainbow baby! First pregnancy symtoms my boobs hurt a lot worse and cramped and had back pain more. Also knew I was pregnant before my test. Hoping this is the same!
