If you started Clomid today and today is cycle day three (3) then you would take it until cycle day seven (7) with cycle day seven (7) being the last pill. That will be 5 days because you should have 5 pills taking one (1) pill a day. With all that being said according to the Clomid Ovulation Calculator
you take Clomid from 12/2/2016-12/6/2016
you would expect to ovulate between 12/11/2-16 and 12/16/2016
if you use ovulation predictor kits then start testing on 12/9/2016 until you get your positive. Positive test is when the test line on left is same color as or darker than control line on the rigjht, Indicating ovulation will occure within the next 12-36 hours.
Optimally you should start making lover every other day starting 12/9/2-16 up to 4-5 days after your 1st positive OPK. When you get you first positive OPK no further testing is required.
Hope this helps and good luck
