Hey there, to start I'll tell you a little about me, I'm 20 yrs old (nearly 21), live a normal lifestyle even though at times can be quite stressful, came off the implant last August (2014) as it was causing complications.
Right, since I had the implant removed I went straight back onto my regular periods, the last week of every month. Never been late or early since, but this month was different.
I had my last week of the month period as normal, being stroppy, regular flow, everything as normal and then I come off. A week later or maybe more (no later than 2 weeks) I came on again. But it was different.
(Without sounding disgusting) this time was like a brown discharge but lasted for 4 days about a light-regular flow. Enough for me to use tampons anyways. This isn't normal for me I have always been a creature of habit.
So that happened then I came off, since then a couple other weird things have happened, ive become slightly emotional, different food cravings (but I do love my food and vary from time to time what I fancy), having waves of sickness feeling without being sick (only once) and having hot and cold flushes.
Normally I'm a solid sleeper, and could sleep through an earthquake but last night I was so restless, up every couple of hours to pee and constant bellyache, similar to period pain but not as bad, more of a discomfort.
I've done pregnancy test coming up negative, but like I said being a creature of habit this is quite worrying.
Anybody had anything similar or knows what's happening? 
Any help or advice would be much appreciated
