Implant removed!

Lisa

Got my implant removed on march 6th 2018 .me and my fiancé are trying for our second I know it may take a bit to get pregnant but does anyone know how long the implant is out of your system.I started spotting last night and still and am today .. my periods have always been mixed up it's hard to keep up with my cycles I can't remember the last time ive had a period even before I got the implant I had the implant for 1 year and never had a period with it.so how do I know if this is a period coming or early sign of pregnancy?
