There are also supplements you can take: to increase your cervical mucous, try taking Evening Primrose Oil until you ovulate, and drink lots of water which also increases mucous.

For DH, supplements which might help include zinc, selenium and from memory saw palmetto. I remember a friend years ago was told she and her DH had almost no chance of conceiving naturally due to his sperm motility, and he took supplements and hey presto! a beautiful daughter. (It might be an idea to google male fertility supplements.)

You will get tons of advice on the ttc threads. Good luck!
