I am 33 with 2 DC who I conceived at 27 and 29 on the first attempt each. I do not remember how long my cycles were pre DC but DC2 was conceived while breastfeeding and a short luteal phase. I now have a copper coil and apart from some mid cycle spotting I wonder if my periods are irregular and if so whether that's due to the coil or whether it's me and says something about possible fertility issues. My last few cycles were 23, 33, 26, 28 and 24 days. Does this sound problematic or fairly normal?
