Cramping and spotting

So I've had mild cramping for 2 days now. Today I've had some brownish spotting. I'm not supposed to start until July 11. My last day of ovulation was June 27 and we did BD on that day. I've also been really naseaous and threw up all day yesterday (pretty sure I had a virus) I've also been extremely tired. I'm just wondering if anyone had these symptoms in early pregnancy or is this just pms...
