I am sorry but it is late and my mind isn’t going the way it should be….there was an episode where jack got stranded of world. There was a meteor shower and it berried the gate. Jack started living with a woman and at the end of the episode it made it sound like she was pregnant by jack.
I own all 10 seasons of stargate…is it me or did they never explain if he had a child with her?

Not just you. The ep you're thinking of is Season Three's "A Hundred Days". They kept it very open at the ending as to whether she hoped there would be a child or she thought there would be a child by the way she held herself.
Fanfic abounds with all sorts of scenarios, but there's nothing concrete.
The closest you get is one of the scenes in Season Eight's "Citizen Joe" when the guys in the barber shop wonder whatever happened to Laira.
