Fetal hiccups

Anyone else feeling fetal hiccups? I started feeling them around 28 weeks. It's not an every day thing, maybe once or twice a week. The hiccups lasts anywhere from 1-3 minutes. I'm 32 weeks today and it's been about 5 days since babe last had a hiccup episode. Google has mixed reviews about them... (ugh shouldn't ever google). Reviews like cord compression freak me out. Also said they should stop after 32 weeks, or be less occurring. When I do feel them it's not several times in one day, just once and always random. My baby is very active all though out the day, so I haven't had any concerns. What has your experience been with fetal hiccups? Should I discuss them with my OB at my next appointment?
