@mamaoftwo Overall, symptoms or lack thereof aren't really an indication of anything -- it's possible either to have or not have subjective symptoms in the environment of healthy progesterone levels. There's no real "should" for what you feel, and it's fine to have whatever set of symptoms you have. These symptoms are not directly reflective of either progesterone or estrogen levels, and they don't tell you whether the cycle will be successful.
The term "estrogen dominance" is used more in the context of non-medical information about the cycle -- it's normal for estrogen levels to be high, even during the luteal phase, and there's not really evidence that "estrogen dominance" is an actual unique problem. I find it exceedingly suspect that most sources talking about estrogen dominance will list symptoms that are plainly attributable to progesterone levels -- for example, when I was taking progesterone for a fully medicated embryo transfer cycle, I had tender breasts and other symptoms that many of these sources would claim are due to estrogen dominance, but I had bloodwork to confirm that my estrogen and progesterone levels were as expected for the transfer. For the most part, I think most sources that talk about "estrogen dominance" are just trying to convince you there's something wrong with you.
When progesterone levels rise, this is what causes BBT to shift. It's a bit of a backwards mechanism: the rise in progesterone causes temps not to fall as far overnight, which appears as a shift in the chart when you take your temperature at the same time each day. But it's not actually raising your core temperature throughout the day, it's just not allowing it to fall as far overnight.
