Ovulated on November 16th, and had sex on the 15th, 16th, and 17th, and started noticing nausea by the 18th, followed by headaches, tiredness, loss of appetite. But the loss of appetite has subsided and now I'm just starving all the time. I know it's still really early, but like most of you, I know my body and I know something feels off. But my question is, did anyone else just have a super annoying headache day after day after day followed by nausea as an indication you were pregnant within the first two weeks?
