Doctor at 8w

Hayley • 32 years old. MMC 8/5/16 at 13 weeks. My rainbow baby, Milo Wild, was born 8/30/17! 🌈 Chemical 11/2020. Baby girl Due 9/9/2021! 🌈
Is there anyone else whose doctor won't see them until 8+ weeks? I had a miscarriage a few months ago and just recently found out I'm pregnant again. They will see me when I'm 8 weeks but they don't even do blood tests or anything before that. I'm so so nervous and questioning everything. My loss was a mmc at 13 weeks, but baby had stopped growing at 6. Any insight or positive stories would be helpful. I'm a mess!
