Ways to boost immune system first trimester

[l0psy]

Just wondering if anyone has any safe ways to boost the immune system during first trimester? Feeling like i have the beginnings of a cold coming and i want to get ahead of it if possible!

I don't have any immune boosting tips, but if you haven't had your flu jab it may be a good time to get it booked in.

Probiotics! Proper ones from the pharmacy.
