Does improving your fitness by a lot reduce blood pressure?

Another question: What are the chances of a 15 year old with primary hypertension to get a heart attack?

When do you get your period with loestrin 24 fe (i.e., do you start on brown pills)?

I just switched to Loestrin 24 fe and am on day 25 (the first day of the brown pill) and just wondering when you typically get your period. I used to get it on the third day or so of Ortho Lo (green pills), but there were also seven of those inactive pills, and only four here with Loestrin. Thanks!
