I never had these symptoms the first time...

I’m so tired all the time and I keep randomly getting mad or crying and feeling totally down. Then ten minutes later I’m completely fine again...? Is this abnormal or just hormones? Last pregnancy I was getting terrible morning sickness by now (4 weeks 6 days) and sleeping all day but none of the mood swings 🤷🏻‍♀️ my doctor won’t see me until 12 weeks so I’m getting really nervous something is wrong. I’m only mildly nauseous this time around and other than being tired and crampy I have no pregnancy symptoms. I feel like the first pregnancy hit me so hard with throwing up, breast tenderness, etc...
