False positive with FMU on Ovulation test?

Question

I am very confused. Yesterday was CD 15 and the ovulation test showed positive first thing in the morning. Last night, it was negative. This morning, CD 16, was positive again with FMU. Am I getting false positives?

Answer

Apparently FMU can give you false positives...personally I've never had a false positive with FMU. If I get a positive with FMU, I will get another positive also later in the day. But perhaps this is your case if you had a negative and then a positive again with FMU?

Answer

I think it depends on the test. My Clear Blue digitals tells me to test with FMU, while Wondfo says not to use it.
