Pregnancy symptoms

Jessica • Mother of a 12 year old Son, 9 year old twin daughters and a 1 year old boy.
One minute I'm freezing next I'm burning up. I'm tired all the time and constantly gasey. Acne is also bad. I don't remember my other pregnancies being like this. I wounder if it's cause I'm older. I slept all night 8 hours and had to take a nap around 11:30 I didn't wake till 3:30. Anyone else having same issues. I'm 9w3d due July 11th.
