Seeking advice from moms who have taken the exam

I’ve seen posts from pregnant women and new moms who have inquired about whether to take the exam. If you’ve taken the exam while breastfeeding, could you share your test day experience and how much time should be allotted for bathroom breaks and/or pumping? I can handle the studying part (props to my very supportive husband), but I’m not sure how test day would work. (I passed L2 and am debating whether to study for L3. If I don’t do this now, it probably won’t happen for several years.)
