Confused

Hi can any one help me I had my implant out on the 9 th jan and have been trying for a baby till now I have had all the early symptoms but last two days I have had chronic pains in my left lower belly area but I have never had pains like that before due to come close to my period but I started bleeding last night but it was extremely baby pinky colour but now it's gone to a dark brown colour and very light bleeding than my normal period ... Girls please help I'm very confused ;) Thankyou ;) xx
