Remove myself from groups?

Sarah • TTC since April 2016. MMC #1 Sept `16 MMC #2 Jan `17 Ectopic and Tube Removed Nov ‘17
I was due in April but had a miscarriage, I changed the setting on glow however I'm still getting updates and am still a part of the 'April babies' group and it's getting me down, how can I remove that group?
