Periods

The kind of periods that i want to talk about are no doubt about female periods. Not in the sense that its a monthly repetition kind of thing but more of the effects on the person and the people around them.

Some girls will claim that they will have bad stomachaches until it really disrupts their life, some claims to have no ill effects and etc. So what the hell is really happening? For those who show signs physically, of course one will get the plain fact to avoid any issues with them. For those who claim that they suffer no ill effects, to me still show some signs of change in their attitude.

The change in attitude can be seen or heard when they flip out, out of a sudden when in normal times they would be more calm in resolving some issues. A normal touch also can set them off. In some cases, you just want to care for them, sigh.

Are there anymore signs which one should look out for? Ladies give the guys a hand, please.
