Are these mundane "extent pains"?

Okay, so I've only have my period in the order of 2 years now. And this second period, which be a few days ago was really unpromising. I experienced this wierd feeling, contained by which all of the muscles contained by my legs felt vague at first, (is that normal?) and next the cramps came and adjectives of my legs hurt. I had fatigue, nausea and I feel bloated. The cramps were awful the first daylight when it came, and consequently they were mild and finally they go away. But then again, here I am at the finish of my period (about 5th day) and I've get that wierd leg thing again, where on earth all of my leg muscles consistency like jello. I can totter and everything... I'm just wondering if this is commonplace? About 3 years after I had started have periods they completely changed. I started getting backache down into my legs and the cramps were severe. They would capture bad consequently ease...next bad again. I would also throw up.
After I have my first child I realized that my body must hold thought I was contained by labor every time I had my interval. I was in reality having contractions...to be exact why it hurt all the bearing into my legs.
I hope this does not happen to you and that it is in recent times a one time occurrence.
you may hold just have a little valise of a virus. that's how i was adjectives last week short my period.
