Nexplanon and ttc

So I took out my nexplanon June 20th. I've read it could take time for your cycles to regulate back to normal after, but I'm on cycle day 55 or more and still no period! Is this normal and when should I expect a regular cycle? When I got it taken out I was on my first real period in about a year, but it ended 2 days after I got it out (lasted 4 days). Lots of discharge, negative pts once a week in July and negative last week around August 1st.
