Can vitex mess up ovulation and mess up the chances to conceive?

Michelle
Thinking vitex would help me produce more cm and just have a higher chance of becoming pregnant I starting taking it two weeks ago.  I have a very exact cycle day. Of 28. Day 14 is my ovulation day usual and cramps are my exact signs and cm on day like 12,13. I haven't gotten a positive ovulation line since taking vitex. So upset :( my significant other and I have been trying faithfully this time. Hoping I didn't mess up the chances to conceive this month.
