Booster shot

Hello mommies, I'm in my 33rd week now. I just took my flu jab at KKH yesterday (26/4). I asked my gynae, when should I take my booster as I already got the message twice from MOH. She told me to take it a week after my flu jab and not nearing to birthing time. Now Hari raya is coming, I wouldn't want to be sick during this timing if I were to take it next week(which is 1st week of Hari Raya) . OR should I take it after birth itself? Opinion please. Thank you.
