Is it possible to have a period with no cramping?

Yes: But most of us don't have that kind of luck. For everybody else, i suggest an NSAID such as Ibuprofen or naproxen, started at prescription strength doses 1-2 days before you expect the cramps. They work much better if they are in your system when the problem begins, instead of waiting for the cramps to get bad & playing catch-up.

Period no cramps: Yes of course periods are physiological occurence and happens to all females starting puberty and majority do not get cramps and do not need anything during the periods.
