The Missionary Position (man on top) has been said to be the position for conception, however their are no conclusive studies performed regarding this issue. The reason this is believed to be the best position is that it allows for the deepest penetration, getting the sperm closer to the cervix. You can also try having DH enter from behind (Doggy Style or Rear Entry) , either lying down or kneeling, this can also help to deposit sperm close to the cervix and aid conception. This is a good option for women with a tilted uterus.
After intercourse, try putting a pillow under your bottom, elevating your hips allowing for more sperm contact. Stay there for at least 30 minutes. Why make the sperm fight gravity on top of all the other obstacles it has to get through to get to where it needs to go.
Note: If you are predisposed to getting urinary tract infections and advised to go to the bathroom immediately after intercourse, do so.
