What should I do?

I've been with my SO for 5yrs and we've had our ups and downs but we're sticking it out and want to be together. He got a job at Sanitation, so he's been doing doubles and he comes home tired and sore. I'm 2mo late on my period and I told him, but it doesn't seem to phase him. I took a test last week it, there was a faint line so I decided to wait to take another test. But it seems like he doesn't care. He's always asking me to massage him, his arm, his back, whatever and I do it. But I ask for him to return the favor, and it's like pulling teeth. He doesn't do it at all. I'm really starting to think I'm just here for nothing, and if I am pregnant, that I will be doing this on my own. I talked to him and nothing is changing. Am I expecting too much, reading too much into it? What should I do?
