Low milk supply during periods

Is it normal to have a low milk supply before and during po ng menstrual period? Based on my observation, ang konti ng pumped milk ko everytime na magkakaroon at meron ako. Even kapag nagdirect latch si Lo pagkuwi ko after work, hindi pa nagtatagal feeling ko emptied na yung breast ko. Medyo nakakfrustrate mga Mamsh 🙁
