I am 8-9 weeks pregnant and I am finishing up a a semester in college with my chemistry class. I did not know I was pregnant until a couple weeks ago and as soon as I found out I emailed my chemistry professor and told her in case my lab sessions were considered unsafe. I never received a response from her and if I don't go I will fail my class. I only have one lab session left, do I take the risk and just go and do it? any ideas? obviously the professor doesnt care too much since I never got a reply if there would be a way around it.
