I used to be regular as anything. Six days on, day two and three always the worst, tailing off till day six where I could get away with a thin pad and not a care. Then last year I had a D&C with an immediate Levosert implant (like a Mirena) Without going into detail I had to remove it in October, because I reacted to it badly - I felt like I was constantly living with PMS, always miserable, mood swings and paranoia. There were days where I would sit and cry over nothing for an hour. After removal I felt fantastic, back to being my old happy self. Except for one thing: my cycle is now way off. For the first three months I was down to four dayers, but the last two have only been three days each, and a very light three days at that. Now I've started again, four days early with none of the usual warning signs. I guess maybe related to the removal of the Levosert and my body remembering what it's meant to be doing. I'm 27 and relatively healthy but this is starting to bother me a bit.
