How to make extra money?

My boyfriend are I have the chance to move into a house together for 750$ a month. I’m not currently working and I’m due December 9th, then won’t be able to get a job for a few weeks after that. But in the mean time I just want to contribute in some way, because his job doesn’t pay that well. First month is due December 1st, and I want to try to get enough money to at least pay half or just pay something. I could try selling some things.. I just wish I knew of more options than those like 5 cent surveys online that are truly not even worth it lol. Anyone have any ideas?
