First ultrasound after ectopic pregnancy?

Reb • 👦🏼💚👼🏻🤰🏼💙

September 2017 I had an ectopic pregnancy that ruptured my tube. I was left with only one working ovary. I was 6w4d. Yesterday 3.1.18 I found out I’m pregnant! I called the dr and they don’t want to see me until 8 weeks. I’m worried that it’ll happen again and this is my last chance. I just want the peace of mind that baby attached in a good spot 😔

Anyone have a similar situation? When was your 1st ultrasound?
