Hi Aling,
I’m sorry to hear that you’re not well at the moment and facing a dip in your supply.
Yes! You can certainly get that supply back up - most mamas find that having a nursing holiday helps where you just drink lots, eat happy food, watch Netflix and latch as much as baby wants to latch.
Lots of skin to skin - where baby’s skin is on yours with no barrier or clothing - helps tremendously!
Here’s a great article for your reference:

The aches may be due to side effects of the vaccine as some mums have experienced.
Might I ask which indicator has caused you to infer that your milk supply has dropped please?
