Aw @rachael321 it sounds like you've had a lot on your plate, I really feel for you as I've gone through similar myself, and ended up off work sick - with a cold, but I took a few more days than I needed as I needed it mentally! Didn't want to admit it at the time but I've now told work and they are being really supportive.
I hope you feel better soon with taking work out of the picture. Are work going to be supportive in helping you manage stress when you get back?
I found stress just affects libido to be honest, but it makes sense to also be in the right place mentally to have a baby, and our bodies must know when we are not!
Hope you feel better soon xxx
