Hey ladies!

Quick question as I read all the time on here about nausea starting as early as 4 weeks! I am 5 weeks 6 days and don’t feel any nausea at all? Is this normal? My only symptoms are being a little more tired than usual, constantly need a wee, mild on and off cramps in lower abdomen and some days have mild headaches (in the mornings usually and then it goes when I drink water)

Thanks! 🙈🤷🏻‍♀️
