On CD 15 and now 16 I have been getting a random sharp pain in my cervix. Yesterday it wasn't as bad. Today I felt it more. What is going on? I have been trying to get pregnant for 15 months with no success. I started taking Vitex about 6 weeks ago. Could this be causing it? I doubt it has anything to do with pregnancy because I never seem to ovulate. Working with a doc now on trying to see why.
