Dd1 i had to take mine off at about 20 weeks due to swelling, put it back on a week or so after she was born.
Dd2 i didnt have one so didnt matter lol
Dd3 i took it off about 12 weeks due to weight gain and swelling.
Dd4 i took it off about 30 weeks for the opposite reason- lost so much weight they were falling off my finger! I put them in my jewllery box and dd1 raided it and lost them
