A pregnancy question?

my last period started on september 30th. so far, i have had on the 2nd, 3rd, 4th, 5th, 7th, 9th, 10th, 11th, 12th, 15th and 17th (of october). im pretty sure i ovulated on or around the 15th. i usually have 30-32 day cycles. what do you think my chances of concieving are?? ive been feeling slight nausea,but not to the point of throwing up. i have these white dots at the tips of my , cramping in my lower abdomen, and last night i felt these strange twinges in my belly that woke me up, but they werent painful. ive been trying for a year now with my husband and im hoping this is my month!!! please help!!! thanks!
