So my little sister swears up and down that she knows that she is one week pregnant and I told her there's no possible way you could know already she swears up and down she know the date you conceived the position she conceived and everything but I don't believe there's no possible way and since I use this app with my first pregnancy I decided to come to you for I guess if I see anything you can give me

So the question is is it possible for a woman to know that she's pregnant at 1 week pregnant or is she just making it up in your head because she wants to be pregnant she also sent me a picture of her fertility calendar tell me if it makes any sense to you people because it doesn't make any to me
