clomid side effects

I'm 31 and on my first month of clomid.  It's currently 10 dpo so I took a pregnancy test this morning and got a bfn. I really thought this would be the month (we're on our 17th month of ttc) because I'm having all new symptoms before my period...tender breasts, tiredness, mood swings (I had a full on meltdown earlier today when I spilled my water on the carpet), and occasional nausea. I know that clomid can mimic the signs of pregnancy but I am wishfully hoping that it's still possible to be pregnant.  Has anyone else experienced these symptoms while on clomid and gotten a bfp after 10 dpo???
