Ok so I'm on the birth control that's the implant . And I got it February 22 and now it's March 9th . I haven't gotten a period yet on it . Before I got it I just finished my period so my next period that's coming is March 12 . Today I found this weird type of discharge or its just spotting in my panties . I don't know what color it is because my panties are a bright red . But it's showing up a dark color on my panties like brown close to black . Any ideas ?? Has this happened to you ??
