Losing my supply :( HELP

I’m a little over 7 mpp and have been exclusively pumping the whole time. I have been at 4ppd for the last month and a half or so and have been able to skate by just barely making enough for baby, some days not quite and that’s fine, we combo feed when needed. But this past weekend I got sick with the cold/flu and now I’m down a whole 5oz bottle worth of milk for the last two days and I am freaking out. I really don’t know that I have the mental capacity to add more pumps in. I’ve been drinking fluids like crazy and making sure I’m eating yesterday and today.

I guess I’m wondering did anyone’s supply drop while being sick and then it went back??? Or am I screwed and this is my new normal?
