Brief Answer:
Brown discharge is your periods

Detailed Answer:
Hi,

I understand your concerns.

Brown discharge is likely to be your periods.

After implanon removal first few periods will be like this. Irregular and reduced flow.

Wait for periods to regularize. Meanwhile keep trying for pregnancy. Ovulation will also be irregular and might ovulate anytime leading to pregnancy.

But it's difficult to predict next periods exactly, please try t understand

Let me know if you need anymore help.

Brief Answer:
Hi, most likely due to progesterone hormone effect

Detailed Answer:
Hi,

Initial couple of cycles will be like this. This is due to high progesterone hormone levels in body due to previous implanon.

This was definitely your periods though it was light. Don't worry.
