I'm not so sure I like this new midwife

Ok so I have a dilemma. I love 3 of the remaining midwives at my practice. I haven't meant one of the new ones. But this one. She told me 13 weeks is too early to have a mucus plug (it starts to form around 7 weeks) she was looking at the wrong place for baby's heartbeat and didn't really find it at 12 weeks. I'm just wary at this point. However the midwife that delivered my son is still at the practice....I just dont know how comfortable I feel with her...
