11dpo am I out this month ??

I think I'm 11dpo but I'm not 100% sure as I didn't pick up a positive ovulation test this month as I think I tested to late any way I've just took this pregnancy test just to see as I've been feeling a little sick an been having mad cramps but its negative so could I be out this month ? Ive never tryed these boots be4 so I don't no how good thay can pick up hcg ? I did won't to buy the first response but thay didnt have them so this looked like them so I got this one ? Would i get a faint line even at 11dpo ?
