I'm 33, 34 in The summer. I moved from he combined pill to the T380 copper coil in August 2015. My period was a lot heavier for the first 9 months after, but probably just normal. I got my very first period before my 16th birthday and started the pill at 16 too. This means that I didn't really have that many natural periods before the pill.
For the last maybe 9 months I have had the weirdest periods. The cycle seems roughly 21 ish days but spotting for maybe a week before, the period is light and then spotting for maybe 5 or so days after.
I had my last smearing February 2017 and all was normal.
I have rosacea and it has been really bad and bumpy recently and I don't know if this is connected. I started erythromycin last Friday for my face, but no change yet.
