Don't know what is going on with my body

Last week was my fertile week and we BD all that week and the week before that. Lately I have been very moody, sensitive and have bad break outs (I dont usually break out) I literally cry for every little thing and get irritated easily. My mother passed away almost two months ago and I don't know if all this is happening to my body due to grief or my body is getting ready for a pregnancy.
