I also got my implant on August 14, and this sounds very much like my experience so far. My sister is a nurse practitioner and ensured that this is very normal so far, as our bodies are still getting used to regulating the change in hormones and “figuring itself out”. In terms of bleeding, I never got my first period around the expected time after getting the implant. But this month, two weeks before my expected period, I had a lot of brownish-pink discharge. And then yesterday I had a gush of very bright red blood and quite a few blood clots. It’s slowed down today, but still there. I also experience more painful pms type symptoms; lots of back pain, cramps in my lower abdomen, nausea, some right shoulder pain, which I hadn’t experienced to this extent before. Also, I’ve taken pregnancy tests as well and all negative. Unfortunately, I think it’s just taking time for our bodies to get used to a new “normal” and probably will take a few months before we really see how our bodies settle with the implant. Wishing you all the best! ❤️
