6 week ultrasound- measuring 5 weeks

Nicole

I’m supposed to be 6 weeks based off ovulation. I used the opk sticks. I went today for u/s and gestational sac is measuring 5 weeks and it’s empty. I’m having a hard time being positive especially because I know when I ovulated. I had miscarriage 8 months ago and I’m old (40)!

Success stories out there??
