My nipples only begain to hurt so bad an they are still...

Hi. Me an my husband have been ttc for three years. I took 50mgs of chlomis last year for 33u months. I started it this year an for three months. This is my third month an i took150mg. I started my period in the 11th (march). Since my period are between 39 to 45 days apart cause i have to have a shot to have my period my cycles are farther apart. I ovulated on the 30th an i took a pregnacy test on the 4th. I knew it was to early but i did it anyway. My nipples only begain to hurt so bad an they are still so sensitive to the touch on the 3rd. On the 7th i started getting crampy an i threwbip that day. Anyway does it sound like im pregnant
