What to expect...

So I was on the depo shot for 9 months, and then my period didn't return for over a year. Now that I'm getting my period, it's all over the place and lasting 10-12 days at a time. My gyne talked about moving forward with assisting with trying to get pregnant. I'm super nervous, I have no idea what to expect. Anyone willing to explain their journey? I think she has suspicions that we're going to require ivf since she had me get pre approved through my insurance. So I'm kinda hoping you can tell me what to expect next 😕
