Did you discuss maternity leave with your employer at the same time that you told them you were pregnant? If you waited until later, when did you have that conversation? This is if your company did not have a clear policy outlined.

My boss already knows I'm pregnant (I told her at 6 weeks) and she said we would just discuss leave later on once I was out of the first trimester. I want to bring it up at an appropriate time, because I'm not sure what they're open to. I'm definitely coming back afterwards, but the only person who's had a baby while working here is my boss, who owns the company lol.
