fundal height measurements?

Leeeilaaa • Mama to both 👸🏼🤴🏼

I don't know if anyone else has experienced this or not. At my obgyn they rotate you around so you get to meet all the doctors. Well 2 weeks ago I had a visit with my regular obgyn & she marked my fundal height at 29 weeks which is perfect with where my pregnancy is at. then this week I visit a different obgyn and she says my measurement is only at 25 weeks for her. So now I have to get an ultrasound done this week to make sure the baby is fine. I'm wondering if anyone else has ever had this happen and if maybe she just measured weird or something.
