Weird Periods. Is This Common After Pregnancy?

VERY common for your period to change after a pregnancy. Actually, it's less likely that it would be exactly the same. Between PMS symptoms to length of cycle, and time you ovulate even if you tend to have the same number of days in the cycle, all of the above, and more...can be "messed up" so to speak! (That's why you might notice a lot of women who use natural family planning methods end up pregnant within a year following having a baby even if it worked like a charm for years!)
You'll find your new normal. I had lots of changes, and after my DD, my cramps became unbearable (they were bad to begin with), but after DS, they've pretty much disappeared! Some good can come of it! =0)

Well, your body may still be adjusting from having a baby. But in some occasions you dont get back the period you used to. like with me before having my child i would get my period 4 regular days no cramps, bloating or anything. My baby is now 20 months and my periods are exactly as you describe. don't know if your on it but birth control also plays a big role on your period. I wouldn't worry for now but if cramps get worse or stronger pains begin i would see a gyn.

Very common...but lucky for me my cramps are not nearly as bad as they used to be...My first year after my son was wacky...He hit the year mark and I've been normal for about three months now.

It can take a while for your period to stabilize, particularly if you are nursing.

I had a rare situation where my period didn't stabilize and after two years, the period just stopped. We later found out that it was due to an elevated level of prolactin, caused by a pituitary tumor. This is an EXTREME case, so I wouldn't worry. Just keep monitoring and tracking your period. I'm sure it will stabilize soon.

In a word, YES. It varies by person what changes you get. It can also be affected by hormones when breastfeeding.
