Hi Karii
I had the same thing, it was annoying when they didn't call me she, her.
In the beginning I correct people, saying that it was changed and If they would be so kind to remember that.
Later I was a bit less friendly by asking if there was something wrong with their eyes, coz I looked like a woman, I talked like a woman and I was behavouring like a woman, the least thing they could do was treathing me like a woman.
Most people I knew get used and were using the right pronoms.
People who were persisting in the wrong pronoms had to leave out of my life. I avoided them.
Most of them came back with the right pronoms.
But like Jessica said, it's a process, people are knowing you by many years and while you were making plans for transition they know nothing.
On a certain moment you came out, for you it's a fact now, but, they need a little time to get used to the new situation.
A good conversation with them, by telling them how it's hurting you by using the wrong pronoms can help.
Because it's hurting, and you're in a quite vulnerable stage, so they can have some compassion with you.
I hope things will come out good for you.
hugs
