What is going on???

Christina • Mom of a 2 year old and pregnant with baby #2!
Just got off nexplanon on the 31st of May. I had a normal week long period from the following Wednesday to the Wednesday after that. And here I am 3 negative pregnancy tests and over a month later and no period. I don't know what is going on. And there aren't too many things that are more frustrating when you're TTC than a negative test and still no period. Is the birth control still in my system? Is my cycle different now? Am I actually pregnant but it's still too early to tell at home? I'm going to make an appointment soon. I honestly just wanted to vent about the annoyance that I'm sure someone else has shared with me.
