Af due July 21st help and do I have any cycle buddies???

Don't know if k ovulated the 7th or the 12th but last three days I've had nausea on and off. First day that night I got a rush of nausea almost threw up went to bed woke up.. Couple hours into work happened again but threw up yesterday I was okay most of the day had light nausea here and there today I am feeling nausea more than yesterday. Increased sex drive like soon after I woke up I wanted to jump hubby. I've had an increase in appetite since the day I threw up which actually seemed like eating helped me.. Took a test this morning but I'm not supposed to start till the 21st and it was pfn. I've also had tmi but really bad gas... What do you guys think??
