Fundual Height measurements….

I had an appointment last week at 33 weeks and 6 days and my fundual height was measuring at 30 weeks, so almost three week behind (the doctor didn’t say anything though) and this week I had an appointment with a different doctor in the practice and I was exactly 34 weeks and my Doctor measurement my fundual height at 35 weeks. I usually check online to see any doctor notes and that’s when I noticed the difference in fundual height measurements. I called today and the nurse spoke with my doctor, which was the doctor I saw this week and measured me at 35 weeks and her answer was just that sometimes doctors measure differently. I’m just curious if this has happened to anyone?? I’m sure it’s fine… and I’m worried about nothing!
