Symptoms going away

Rebecca
Last week my boobs were super sore, I was crazy nauseous all day, and I wasn't sleeping past 5:30. This week, no nausea, boobs feel fine, sleeping till 6. I miscarried in August at 7 weeks (measured 5). Right now I'm 5w5d. Worried that baby isn't growing like it should. hCG was 68 at 4w1d. Don't wanna lose this one too...
