Twitching and flicking

kay
A few times in the day and night I get a twitching flicking feeling to the left side of my pubic area bit it's constant for like fifteen minutes. Flick after flick. I thought it was hiccups and I asked the midwife and she dismissed it and said baby might just be on a nerve. But I don't get it? She is head down I'm 35 weeks. Anyone else experienced this?
