So over the past week or so I've had a lot of pregnancy symtoms. The nausea, cramping, fatigue, headaches, and even feeling pressure in my bottom. Ttc for my 3rd baby so I know what it feels like to be pregnant and that's how I feel. Tons of BD. I've taken a few tests already and all are negative. I'm on cycle day 19. My question is do you think it's too early to tell or could it be something else?
