My gyn put me on estrogen without really discussing much. I was on the patch for about two months and it did cause nausea, though nothing unmanageable. However, I ended up in the ER with shortness of breath, confusion, and dizziness. I don't know if the patch caused all of that definitely, but the symptoms disappeared after I took the patch off.
I've also never done well on BC. I just couldn't do it. Hormone replacement is not for everyone and I really wish doctors would spend even the minimal amounts of time talking to us about it and educating us.
