S/O wanted a baby for 7 months and now he doesn't?

My s/o and I have been actively trying to concieve for 3 months and he's wanted a baby for the last 7 months. Well we got into a fight on Monday that was pretty bad and now he says he doesn't want a baby anymore.. what's everyone's advice on my situation?? My AF is due on the 11th of November and I'm worried if I get a positive NOW that he doesn't want it, it'll just turn into a bigger fight. Opinions? Please 😞😞😞
