Are they expecting me to miscarry?


I will start off by saying I am a plus size woman, 7w2d with baby number one. I keep seeing everyone else having ultrasounds at 4,5, and 6 weeks, yet my obgyn won't see me until I'm almost 10 weeks. My general practitioner doctor saw me at 4w5d and confirmed pregnancy through blood work, but has not had me come back to check levels. She told me not to get too attached as 25% of pregnancies miscarry for one reason or another... at this point I feel like they expect me to lose it and that's why I haven't been asked to come in as often as I'm seeing you other ladies. Am I being ridiculous?
