month long bleeding

i’ve been bleeding for a whole month for the second time. i have the nexplanon and got it in march. before my june period, i would have a regular 7 day period once a month

then my month long periods started. between may/june and june/july, i was just short of a 2 week break between the two.

currently my june/july period is starting to creep into the second month (i can attach a screenshot of what my periods have looked like on the calendar)

ive tried calling planned parenthood for answers but no one answers so at what point should i go in for an appointment or go see a doctor.
