I ovulated a week ago but a week later im still showing positive on ovulation test. y is my ovulation test still positive? today ive been throwing up and diarrhea. my periods are normal 30 to 31 day cycles. period is not due for another week

Stop testing: It is normal for ovulation kits to stay normal for several days then become negative. There is no need to check beyond the initial positive result. The hormonal rise that causes the positive result lingers for a few days which will keep an ovulation test positive. Once it is positive then you should begin having intercourse daily.
