Third pregnancy , feeling awful

Hi! I’m 37 and this is my third pregnancy. Both of my other pregnancies were healthy. I had morning sickness but it subsided at my second trimester.

I’m currently only 7 weeks pregnant and I’m terribly nauseous, I get so light headed that I feel my vision is a little blurred, I’ve been napping for 3 hours the last couple of days. Idk if I’m worrying myself for nothing but I feel soooo worried. Is it bc I’m older? Has anyone gone thru this. My other pregnancies were 31 and 33.

I’m panicking a little and have my first prenatal appt is on Monday. I wish I could call my mother for advice or just to calm my nerves but we don’t have that kind of relationship. Any advice or anyone felt this sick?

Edit: thank you to all the ladies that replied. I don’t know if it’s your reassurances that helped or my prayers. But I feel so much better today! My worry might have been adding to my symptoms. Thank you all!!!!!
