Can anyone ease my mind a little?

I have a history of miscarriage. I found out i was pregnant at exactly four weeks. Two days later my doctor brought me in for hcg and a transvaginal ultrasound. Hcg was at 226, which she said was perfect. My breasts were so sore and I’ve been extremely fatigued. I was very sick this afternoon and i just took a shower and realized my breasts werent sore at all and i feel like i have more energy tonight. I’m almost five weeks now and I’m just wondering if anyone else has had this problem and it wasn’t the first signs of a miscarriage. I’m going to call my doctor in the morning and get my levels drawn to make sure my hcg hasn’t declined.
