Should I count the first three days of old blood?

I started My period on the first and ended it on the tenth. I was told that the tenth day after you count the first day of your period is the ovulation day! The first three days were brown old blood,"spotting" and then more red towards the end! I counted the first three days and checked to see if I was ovulating yesterday and I wasn't Some has said it's the fourteenth day what do you think? we did go ahead and make love last night and I put my bum under a pillow for an hour Oh and she also told me that my husband can have a higher sperm count by waiting 5 days, my doctor said it did not matter he told me to make love everyday? I am confused.
