work problems while pregnant

(Id like to start with i work with toddlers so it's not like a big kid caused this.... ) So I peed on myself at work today. Yup little dark part between my legs came up and all. (Like pants damp) Here is how: so there I was doing my morning diaper changes right, all dandy and I was on my last change before centers time. (Now I'd like to say this before I get into the details. this student normally doesn't have a problem with changes, but today in a whole was kinda an off day. I could feel it too.) I disinfect the changing table, roll out the changing paper, pull out the child's supplies, put on my gloves than go to pick up the said child. as I'm mid lift the student karate kicks me in me bladder I crumble half dropping the student and pee a little. then proceeded to cry. not cause it hurt, but cause I could not believe I an adult just peed. On my self. in front of my students. not that they even knew what on earth happened but still. my fellow co worker laughed and said "welcome to preggers hood!"
