Hiccups loads every day

Hi everyone! Just looking for a bit of advice. My baby girl gets hiccups every day, which I know is pretty normal, but I know that sometimes it can be related to cord issues. At what point do you worry? She gets them maybe 5 times a day and they last about 3-5 minutes. She really jerks with them sometimes bless her! I know it's also a good sign that she's practising breathing, but just wondered if you would seek advice from the midwife? In the UK you don't get an ultrasound after 20 weeks, so it's not easy to keep tabs on her. Thanks in advance x
