To DTD, that is the question!

My husband & I have been TTC for almost 18 months. I am on my 4th month of Clomid. I have been tempting & OPKs for 2 months. Yesterday I got a positive OPK & today was also positive. My progesterone levels have been so high and yet we still have yet to conceive. My doctor suggested my husband get his sperm analysis done again & he did last week. We get the results tomorrow! :) My doctor recommended we abstain for 3 days prior to ovulation to better the sperm quality & quantity, but my cycle is messed up & I am ovulating earlier than expected. It's been 1.5 days since DTD. What do you think ladies ... Should we DTD anyways & hope for the best or wait 1 more day?
