Horrible day yesterday- now I'm worried :(

Victoria
Hi, ladies! Yesterday I had a very emotionally tumultuous day. My fiancé, bless his soul, has been under a lot of stress between finding out about our pregnancy, trying to find a better paying job, moving out of our current home...all topped off with the fact that my hormones have made me very irritable (downright bitchy, unfortunately). Well, the tensions dissolved into an absolute screaming match with lots of tears. We've since reconciled and are fine, but I'm terribly worried about the baby. This is my first pregnancy, and I'm 5w2d today. A few hours after the fight and making up, we had sex and I spotted afterwards. I haven't had any spotting up until that point.
I know that I'm probably worried for nothing, but I could use some wisdom and encouraging words if anybody has any. :) To ease my mind, I bought a pregnancy test that I will take in a little while to make sure my line is nice and dark. My first doctor visit isn't for another week- ugh!
