Why do I tend to bleed on one side of the tampon?
It may be that you spend a good part of the day on your butt. When you're just sitting around for a long time, the blood tends to be on the underside of the tampon. The placement of the tampon also affects absorption. For example, if a tampon rests to one side of the cervical opening, it may soak up more blood there.

Are mid-30s too early for perimenopause?
For most women, yes. The average woman typically hits menopause at around age 51. Perimenopause—the transition phase when menopause symptoms begin—is defined as the four to six years before. 

Why do I have to go (number two!) when I get my period?
Research reveals that your period does affect your poop. One study published in the British Journal of Obstetrics and Gynaecology found that one-third of women without known gastrointestinal problems experience abnormal bowel movements at the time of menstruation; likewise, 50 percent of women with irritable bowel syndrome report exacerbated symptoms at that time of the month. A lot of women have sluggish bowels the week before their period and looser stools for a couple of days after their period begins. Experts suspect that a fluctuation in the hormone progesterone may be the cause. 

I've heard about feeling irritable during PMS, but what about feelings of insecurity or jealousy? Are those PMS too?
Yes. These emotions are part of the symptoms of PMS, and they may put you in a fighting mood. You may want to put off dealing with relationship problems or rearrange your schedule to avoid them. You could also try following a plan proven to reduce emotional and physical PMS symptoms: cut caffeine, increase water intake, and take a multivitamin or PMS-formula vitamin.
