Looking for positive vibes

My husband and I went in for our first ultrasound. Technically at 5 weeks, 6 days based on our IUI date. There was a gestational sac and yolk sac but no fetal pole. My husband andI Immediately  think the worst as we've had a miscarriage but the doc and sono person just said some back in a week because we are right as the "cusp". I feel like they are trying to spare our feelings or something. This week long wait is driving me crazy... Just looking for those to think of us and hope for the best, but we want to be prepared for the worst too unfortunately.
