This kit is the perfect combination of strips for 1-2 months of testing.  20 Ovulation strips should be enough to track and target your LH surge and the 5 pregnancy tests should be enough to find out if it worked.  If you're more "test happy" there is also a 40 + 10 package available.  Simply dip the strip into a urine specimen and allow 5 minutes for development of results. The test strips comes individually packaged in a foil pouch.  Expiration date is 2013.
