Hello, Ovulation occurs two weeks prior to the onset of the next menstrual period in usual circumstances. The influence of the hormones can be seen as engorged breasts, tenderness, bluish discoloration around the nipples, cramping dull pains in the lower abdomen as the ovum is released and traverses the fallopian tube. Unless you have been noting down the basal body temperature from day one of your cycle which shows a mid-cycle surge following ovulation which persists if conception has occurred, it is too early to test. You need to wait t least until a week after ovulation to get the blood test for pregnancy done. Hope this helps.
