Tdap after 36 weeks?

Hi ladies,

I’m currently 36+3 and have completely forgotten to get my tdap shot. I know they say it’s most effective to get it before 36 weeks but has anyone gotten it after that time frame? My dr says it will no longer be effective for the baby because I’m past 36 weeks so it’s up to me if I still want to get it or not... any advice is appreciated 🙏🏻
