Bleeding with Decapeptyl 11.25mg

[teenamac]

Hi again folks. Really strange question as I'm still new to all this...

Is it normal to have a darkish coloured bleeding 5 weeks into the 3 monthly injection? Not quite sure if it's a normal side effect or if it's just me. Wouldn't say it's extremely painful but there is a bit of discomfort.

Many thanks on any answers or advice x
