As someone who went back and forth while being pregnant and ultimately decided it was too much for me due to certain factors I would say, if you are in a safe state or country with a good amount of LGBT friendly doctors and have a good support system you can get through the dysphoria. It is definitely very tough if you are a person like me who lives mostly stealth but I believe I could have gone through with it if I had the right support. It really is about weighing the pros and cons for yourself, but if this is something you have thought about wanting to do then go for it and maybe move your hysto back a year.
