Multiple IF to show different statuses

Hello, I am trying to have different status in my reports depending on the dates in different cells
H START
I ACTUAL START
J DUE
K DATE COMPLETED
L OVERDUE WEEKS
M STATUS

I have the following and it works (this is in M)
=IF(K3="",IF(L3>0.15,"Overdue","Open"),IF(L3>0.15,"Closed Late","Closed"))
overdue
Closed Late
Open
Close

I want to add to M if there is a date in I (actual strat) to show "In Progress" if the start date is the week to show "start this week" and if the due this week to show "due this week" But i am not sure what add
