maternity leave

Just wondering who is working up until their due date and who is picking a day and taking leave early? My work has been so stressful lately and it's hard to leave it at work and not bring it home. I've had what I think are anxiety or panic attacks (dizzy, light headed, can't catch my breath) 3 times in the last two weeks while at work. I was planning on working as long as I can, but now I think I'm going to leave early and take some time to relax and get last minute things prepared. Due May 24th and thinking of my last day being May 12th or 19th...
