Pregnant!? Maybe??

I've had a pregnancy scare, about 3 days ago I was spotting. I'm still 2 days before my scheduled period. I took a pregnancy test yesterday, it came back negative. But I'm still feeling the symptoms like light cramping, tender breast and feeling nausea all day! 
My fiancé is so scared, I know he wants a baby, but not yet! His family is strict Persian and his mum would kick us out of the house. 
If it turns out I am pregnant and abortion isn't an option at all for me, but I think my fiancé thinks it might "fix" the problem. Help!! Has anyone been through something like this.
