Hello everyone. I have a question. On Monday, I had an ultrasound, and my period was then on day 19.2. But according to the ultrasound a week later, they said it was shorter, but everything was normal before, all matched, even showed up for 4 days more, but now it's much less than a week. I got the ultrasound done at a different place than usual. The doctor didn't say anything about my question. I'm feeling a little anxious.
