Help me

Last period was 06-17-15

It lasted 3-4 days.

I only needed one tampon a day the entire time.

I just ovulated and the last day of ovulation my breast got sore.

Now 3 days after ovulation my breast are swollen by at least half a cup size. I have taken one test 6-4-15 it was negative

Ive been trying to conceive for 3 years
