Trying to get pregnant

Well we just started trying to get pregnant so I've let my partner know when the days I'm most fertile well it's been like an act of congress to have sex we've done it two days out of like several days that are good to have sex to conceive, well we were supposed to have sex these past three days but haven't cause it's been to late at night or my partner just doesn't look like he's into it cause of the time. But was willing to have sex just to cum in me. But I was like well you don't look like your wanting to or into it so how am I supposed to be?? Girls help me out what should I do. Currently sleeping in the couch cause he pissed me off that bad so now 3 days missed of having sex...
