The brown widow's legs are darker at each joint of the leg, like this one. And the spots on the back also look right. Body shape for sure. I think it's a brown widow. We too have many of these around our house. Used to have a lot of black widows, but I see more of these now, wonder if they are out-competing the ones we are more familiar with. The egg sac is really distinctive, looks like a spiky little ball. Google the spider, you'll see. I don't think the bite is as toxic as the black widow's.
