A little worried

I had a 13 week ultrasound yesterday and they said everything looks good but I’m a little worried because baby is only measuring in the 25 percentile..also she said that it looks like I have fibroids but she wasn’t 100 percent sure they were fibroids or small contractions! Like what?

Has anyone gone through this or currently? What was the outcome?

I have history of gd, high blood pressure, type 2

I’m trying to enjoy this pregnancy as much as I can but it’s hard when I have anxiety and look so deep into everything
