Losing pregnancy symptoms all at once.

Amy
Should be around 8 weeks based on last menstrual period. I've been suffering with bad morning sickness all day extreme tiredness severe hunger peeing all the time. To the last 2 days absolutley no symptoms at all. All disappeared. I just feel completely different in myself my tummy feels different inside. I've had 4 children so I know the drill of pregnancy and suffered with a lot of symptoms the whole way through each pregnancy to now nothing! So bizarre. My first midwife appointment is Thursday.
