DG, did u check out the site I posted? I did a bit more reading on it. One really interesting thing I noticed was that how estrogenic a given brand of pill is more complicated than just how much estradiol it contains. Its also a matter of the combination of the hormones.
According to this website,
http://www.fpnotebook.com/GYN110.htm
Alesse has a low estrogenic rating (17), a low progestin rating (.5), and a moderate androgenic rating (.31).
Loestrin 1/20 has low estrogenic rating (19), a high progestin rating (1.4), a moderate androgenic rating (.21).
Interestingly, Loestrin 1.5/30 also has a LOW estrogenic rating (13), high progestin rating (1.7), and a high androgenic rating (.8).
The side effects I experienced on Alesse were: break through bleed days 10-21, moodiness, and weight gain (my weight was at 133 on Loestrin 1.5/30, now its 138). The website says all of these side effects are linked to a need for more progestin. It reccommends Loestrin 1/20 as an alternative. However, I like the idea of a higher androgenic rating so I'm thinking maybe I'll just switch back to Loestrin 1.5/30.
So, to summarize, the LOWEST estrogenic rating of all 3 choices is actually Loestrin 1.5/30!!!!
