Working While Pregnant

I've been working full time for the past 6 months of my pregnancy, but now that I've started my 3rd trimester, I am so ready to work part time. In a strange way I feel like working part time is just quitting, and that I should keep working hard. Almost all the women I've talked to say they worked full time and up to the day they went into labor. These comments make me feel like it's weak to work anything less than 40 hours... Anyone else feel this way?
