Pull out question

Viridiana

So I've had the nexplanon (the Bar) for 3 years and got it removed last week and I have a thyroid problem so I don't want anything right now just so I'm sure nothing interferes with my thyroid. ANYWAY! I want to try the 'pull out method' but I'm scared it doesn't really work. Anybody else that has been doing this method and haven't had any 'incidents'? Lol
