Having sex daily is stressful

My husband and I are trying to have our first baby. I got pregnant in November and it ended up being ectopic. I had emergency surgery and lost my left Fallopian tube. I want nothing more then to have a baby, and I started to use the clear blue fertility monitor this cycle in order to increase our chances. The thing is my husband and I are finding it stressful having sex daily. We just are not having any fun or enjoying ourselves since it has become a chore. Has anyone else experienced this? Any advice?? Thanks and baby dust to all!!!
