TTC after a miscarriage

So I have some weird things going on. I had my period July 17th-19th the normal 3 day but lighter than usual. I started noticing bloating and very tender swollen breast about 2 days ago. My boyfriend called me yesterday from work saying he's been throwing up and that he thinks I'm pregnant but I think it's too soon being that my period was less than 2 weeks ago...I am so lost.
