So when would be the best time again??? I know i should have got this down to a fine art by now - but been ttc since May and I am wondering about the days we are bd. Every month i think right this is IT i am pregnant ! my cycles are about 33 days long. I ovulate normally about day 20. I KNOW this!! It's fustrating - should we be bd every day? But then day to day life gets in the way, one of us is tired, husband works late, perhaps he is away on business etc.... i guess bd every day is the only way to make sure. SO when to start? I am on day cd2. thanks !!
