Couple of questions about HRT that are really scaring me...

Really hope someone can offer some advice here. I'm about to start HRT in the coming weeks. I believe it will be Evorel patches and finestride to begin with. I have two real concerns regarding starting treatment though and would be eternally grateful if anyone could offer some advice.

Firstly, I have an absolute phobia of vomiting. I read earlier that one possible side effect of taking estragen can be a morning sickness like nausea. This scares me so much, I'd almost not want to take the risk. Is this a common or even likely side effect?

Secondly, there is a bit of a history of breast cancer in my family. My mom's sister had it and my mother is about to start treatment for a cancer that was found in her breast (caught very early though and is already clear). How much extra of a risk will I be running in taking HRT with this family history? I have read several different takes on it. Some saying it increases the chance a LOT, some saying you're still below the percentage of getting it that a CIS woman is. Is there any generally agreed upon middle ground?

Thanks so much for taking the time to read and possibly answer these questions. I'm equal parts terrified and excited about starting HRT, but I really like to get as much information as I can first. And I know of no better place to ask and get an honest answer.
