Hey there, booknerd. I have a couple thoughts.
First, are you seeing an endocrinologist about your estrogen levels, not just a GP? I ask because I feel like treating that is perhaps something best considered separate from BC methods. I also ask because if that is the case, you using combined hormonal methods that add even MORE estrogen to the mix not only sounds like the wrong way to go for you, but to the degree that I'm actually concerned about the safety of you using *anything* that adds more estrogen (and even more so, taking those methods without breaks). In a word, I'd strongly advise you get a second opinion for a different provider than the one you have been seeing. Unless there's something I'm missing or not understanding here, I'm really questioning their approach.
That all given, I'd expect anyone advising you on contraception to *only* suggest methods that do not involve any estrogen.
How would you feel about a non-hormonal IUD? Do you have heavy or painful periods? If not, a non-hormonal IUD could be in for ten years or more -- that means having it inserted and removed would be rare (and it shouldn't be outrageously painful either: it's very quick, even when it does hurt). It also wouldn't add more hormones to the mix and would allow you to keep having your periods as you prefer. The shot, implant or hormonal IUD would all likely make it so you have spotting, but not so much the regular flow you feel most comfortable with.
