Out of breath / dizziness?

Hi ladies.

I’m 8 weeks and 4 days pregnant and I am feeling ROUGH.

I have horrible sickness / nausea all day long and struggling to eat.

I keep getting very out of breath, light headed, dizzy and also feel like my heart is beating out of my chest. Is this normal? I’m thinking low blood sugar / something with my blood pressure? I don’t have my first midwife appointment for another week and so I will ask then, but just wondering if anyone else has had this / if it’s something to be worried about?

This is my second pregnancy and I wasn’t like this with my first.

I think possibly a lot of it could be due to anxiety of wondering if the baby is ok as we have to wait until 12 weeks for our first ultrasound.

Any thoughts/ tips are appreciated.

Thank you!
