Today I had my first ultrasound. According to my last period I should be 6w6days. However I’m measuring at 5w6d exact. I have PCOS and am wondering if I just ovulated late. There was a heartbeat but it was only 90. The dr told me today as of now they cannot consider this a viable pregnancy because of where in measuring and the heart beat being low. They said we’d do an ultrasound in two weeks and see if it’s progressing. Has anyone else been through this, and if so what was the outcome?
