Regular Periods After BC

I have had the Nexplanon plant since the early summer of 2018. However I just had it removed on Monday. As of the last few months I have been experiencing irregular heavy periods. Some months I’ll get two periods others kid bleed the entire month. Currently I am on day 13 of my period. For anyone who has experienced similar problems while having the same BC if you had it removed how long did it take for your periods to go back to normal? I want to have another baby but with my periods all over the place it may be hard to track
