Thanks for all your inputs

With DD i just knew i was pregnant only days after conception this time i'm not sure. I'm having signs that are telling me. Like with DD i noticed my pee was bright yellow at the beginning and i have that, my boobs feel tingly and are getting darker, my sense of smell has definitely heightened i can smell everyones deoderant/perfume/cologne those who were none at all! bad breath, whether they had been drinking, bad breath.. oh my goodness the works!! im tired, crampy and extremely moody and emotional.
