You may never get PMS at all. Most women who do get PMS don't think it's a big deal. PMS is something that starts happening about 10 days before your period, and stops when your period comes. Pimples or greasy skin, sore breasts, headaches, irritability, bloating and feeling tired are all common PMS symptoms. For instance, a lot of women say that right before their period begins they get a strong urge to clean house, or organize things, even if they are slobs for the rest of the month.
Some women have strange food cravings, or eat more than usual.
Other women cry very easily before their periods, not because they are sad, but because everything seems to touch their heart. If your PMS symptoms bother you there are many things you can do to make that time better.
