7 weeks and nervous!

Jamiya
So my original due date was April 12. After my OB appt, the baby was measuring 8 days early. Well now I'm 7 weeks today (recalculated) and my boobs aren't really sore at all n e more. They aren't just tender when I push to feel what hurts. I'm not bleeding or n e thing so I assume it's just a change in hormones but after a miscarriage already in April, I'm really nervous. I go back for another ultrasound next Friday when I'll be 8 weeks 2 days. Anyone share this experience where all was fine but ur symptoms weren't as severe or went away?
