Should I test or is it the implant?

Elizabeth

i got the implant BC after my first LO was born. She's pushing three months and I haven't have my period since Feb. my period in Feb lasted 8 days and them nothing. i know it was my period and not post partum bleeding, because I had both at the same time. Post partum bleeding stopped, got my period sortly after, little bit of spotting last month, but no period. Should i test or is this common with the BC? i know it is 1 to 100 to get pregnant with it, but maybe im lucky. lol
