I feel sharp pain in lower abdomen which is on and off. Tingling pain in left breast. Today is 9 days post ovulation. Ttc. What could be the causes?

Urine preg test! If you are pregnant the answer is narrowed down to complications of early pregnancy. If you are not pregnant then take your temperature, monitor all my symptoms in a journal and wait and see. I would call my doc too ... To let him/her know things are off.
