I had my daughter on February 20, 2022. So she’ll be 2 next month, right. Well after she was born I got on birth control (NEXPLANON). I haven’t had one period since & I still breastfeed her. Anyways, 2 days ago I noticed that my CM was very faded light pink & yesterday it was light pink. Today was faded brown. I haven’t had to buy and pads for almost 2 years now, so I went to the store to buy some but i don’t have a flow. I did have unprotected sex some time before Christmas?? Should I be worried that maybe the birth control failed me?? Like maybe it’s implantation bleeding??? Picture is from today…
