Twins ??

Katie

We saw the one baby... measured on time HR was 176 at 8w4d. Uterus is retrograde and was hard to see baby at 6w3d. I thought on the first ultrasound there was 2. Hcg levels are super high even for 2 per the doctor. I have a video and my wife and I kept asking each other like “why is there a whole other black hole on the right?”. The doctor said he didnt think there was 2 but didn’t sound confident. Any ideas? I mean don’t get me wrong I’m happy for one baby. Just wondering 😳
