Help! I took benadryl and I EBF

Welp as the title says, I took 1 tablet of benadryl tonight after having an allergic reaction to dinner. I EBF and my supply is established. Took it after my daughter (5 months old) went to bed for the night so I won’t need to nurse until the morning. Will the benadryl decrease my supply or pass through my milk in the morning? By the time she wakes up it’ll be 9 hours after I took it.
