Have the flu and can't sleep. Med suggestions please

K, I'm recovering from the flu. 38+1 weeks and getting induced next week. Been sleeping a lot during the day and would like to take some Benadryl to help me sleep tonight. Benadryl is on my OBs list of acceptable meds, as well as everything else I'm taking.  But since I'm battling the flu, can I take all of this together? Here is a list of all the meds I'm taking. Can I add Benadryl to it?
