I am plus size, size 20, and I didn't start feeling him move daily until 28 weeks. I felt him move a few times starting at 20 weeks but it wasn't very often.
I am plus size as well and I started feeling her move a lot when I was 23 weeks.
I'm not plus sized but two days ago I just felt the first kick from outside I'm 21 weeks,so I'm sure you'll start feeling your lil one soon :)
U will feel it stronger by 22 weeks am near 23 weeks now and starting to see my belly move slightly with kicks x
