So to butt in, just wanted to mention that there is no difference between the ovulation Midstream and ovulation strip test - the midstream test is more convenient though if you need to test in an office environment etc where pulling out a cup and dipping a test in can be a little awkward in front of colleges )
There is a difference between the HCG tests though. The HCG midstream (10miu) is more sensitive than the hcg strip test (20miu).
