  Is it normal to have 16 day cycles?  I have had a Copper IUD for about 4 years. Could that be a reason for it coming so often?

Hi there,

No 16 days cycles are not normal. It could very well be to do with your copper IUD.

Are you having small amounts of bleeding for a couple of days every second time, or is it a full period every time. If you only get a little bleeding every second time, this is due to ovulation, and not a period. That would make your cycle 32 days long, which IS normal.
