Positive OPK?

Please help! I have been tracking my ovulation for 8 months and have not had a positive. This is my first cycle with clomid (ovulation induction) today is the first day that I have had the darkest lines I've seen! Is it truly a positive or am I getting my Hope's up too soon? Dr told me I should ovulate within 5-9 days after I finished medication. Last tests seen are day 7 after medication and also have had egg white CM too! Also those last two tests are same urine different brand test strips. The one taken at CD 16 (AM) the test line was darker than my control line. It lightened a bit since but is this a positive? Help please! 😅
