Nexplanon, now trying to conceive

Hi,

I've booked my appointment for my nexplanon to be taken out next month. Ready to start TTC. Have heard different stories on how long it actually takes for your fertility levels to go back to normal. Doctor has said on average it takes 9months from now to even conceive?! I've had the nexplanon in and out for the past 9 years. Anyone with similar situations? I know all bodies are different. Just looking for some advice so I'm not too excited and ready for a conception straight away if it's unlikely to happen ☹️
