Ovulation surge 5 days in a row! What?

Wendy
Hey ladies! This is my first round of clomid after a miscarriage with clomid in December. The other two times I only had 2 days of surge LH showing I was ovulating. This is day 5 with the same surge. I had 2 negative tests from the same batch before this series of positives so idk ? Anyone experienced long surges like this on clomid or in general??? Eek
