My period ended Oct. 5. I had multiple sessions of sex Oct. 12/13. He came inside me 2 or 3 times. I was nauseous a little Friday night (10/18) and then I got nauseous yesterday (10/19) after eating something but it went away after I stopped eating. I was fine today (10/20) but then I ate dinner and now I’m the most nauseous I’ve ever been. I’ve also been crazy tired. I could barely get out of bed yesterday. I’m better today but in the afternoon, I had to lay down because I got so tired. Isn’t it too early to be experiencing “pregnancy symptoms” ?
