Getting shots during Ramadan

Hello sisters, I haven’t been able to find an answer to this question. I am getting fertility treatments which require getting an hcg shot. The timing this month fell within Ramadan. I finished my medicine but will have to get the shot in a few days and my doctor says it’s best to get it in the morning so that we can do it the next day after futoor. If I get it at night, I’ll miss ovulation since it will be in the morning. I’m wondering if it’s ok to take this shot while fasting. If anyone knows, I’d appreciate any help.
