What kinds of problems do irregular periods cause, for instance?
In the cases I have observed (and I am not a physician), the women have little or no period for several months, and irregularity at that. Then they can have a very heavy flow that is physically hard on them. It’s not a good situation, and it’s one that can be avoided. The use of a birth control pill regulates them, they get normal small periods, and the large physically draining ones vanish.
I obviously can’t say this works in everyone, and there may be good cause to avoid birth control pills for some women. They would have to, and should consult their physician regarding this sort of thing.
Some physicians may actually be against it. I just know what has worked for the women I have known who had this problem.
