Clomiphene - No Cervical Mucus

Q: I have no cervical mucus, what next?

A: Sperm need the mucus to pass through the cervix, and no mucus prevents the sperm from moving up the cervix.
But absent CM could also be a sign that you don't ovulate, so you should monitor for ovulation.
If you ovulate regularly, but you think you have no mucus, an examination by your doctor is in place to verify it.
If you have less mucus while on Clomid, you could take some hormones such as estrogens that could improve your mucus.
