BC when you have high blood pressure?

[hopefullyhypochondriac]

Hi,

I'm a 27 and I've been on BCP for 8 years--about 3 on Ortho Tricyclen and 5 on Ortho Tricyclen Lo. I've always had low BP (110/70 or so) until the past 6 months, when I've developed prehypertension (generally no higher than 135/90 but not lower than 125/82). High BP runs in my family, so my doc really wants to get it down to where it was. I'm 5' 3" and weigh about 122, although I gained 5-7 pounds in the last year or two. I exercise daily.
I've been trying to lower my BP with a very low salt and mostly vegetarian diet (I stopped nightly dates with Ben and Jerry, too), and even though I've lost a little weight, my BP is still higher than it should be.

So, can anyone recommend a different type of BCP that doesn't impact BP? Something with even less hormones than Ortho tricyclen Lo? Has anyone switched to the shot or an IUD and found that BP issues decreased? My doc seems to think the BCP I am on is causing this persistent increase in BP, and I'm guessing if that's the case, it probably won't improve as I get older! Even though I'm in a long-term, completely monogamous relationship (going on 8 years), I'm not ready to get married and don't want kids for a looooooong time (maybe in 5-7 years, definitely not before). The IUD sounds like it might be a good option but I'm a little freaked out by it.

Any advice appreciated :)
