I was only sick on day three but I’ve heard other girls are sick quite a bit afterwards.. Either because of the pain relief, the antibiotics or the stress your body has been under. Make sure you’re drinking plenty of water and try something with ginger in it like ginger beer or biscuits as they’re supposed to stop sickness, alos make sure youre eating when youre taking your tablets, if it carries on contact your nurse or gp and they might be able to give you some anti sickness tablets or change your pain medication xx
