Hello! I stopped pumping when my son was 3 months old and it took about 3 months to get my cycle back. Also, it has changed a bit from what it was pre-pregnancy. My cycle now goes about 31 days, instead of the perfect 28 days that it was before. It's also a little longer and heavier... all things you probably did NOT want to hear, I know. However, my Dr has told me that considering what our bodies go through w/ pregnancy and childbirth, it's no wonder that it won't be the same it was before. She also told me that over time it might change some more and all we can do is roll w/ the punches, haha! I am not on birth control, so I can't comment on if your IUC is affecting the cycle in any way. I hope my comments were helpful. Good Luck!
