I have recently got the contraceptive implant. I am aware that a common side effect is change in menstrual cycle but I seem to be on and off my period throughout the entire month. For example, say my cycle starts, then 2 weeks later I get my period again, this time it lasts longer than it usually does (roughly 7-8 days this time) and then comes back 3-4 days later. I don t know if I should go to my gp just yet, because I don t know if it is something that will sort itself out. So yeah I don t really know what s going on, some assistance would be great.
