I was on clomid and had 5 days in a row last month of + opk. I called the doctor on day 5 because I was concerned that we had mistimed the IUI. The nurse there said that people usually stop testing once they get a +, but she thought it would be within the range of normal to have LH be on the rise for a couple of days, and then on it's way out (but still detectable) for a couple of days. I still had ovulation pain three days after my IUI and supposed ovulation day, which is why I kept testing. Glad to know that I'm not the only one who keeps testing and testing and testing.
