I recently had a period as of April 19th. Usually my periods are on time around every 30 or so days. I did liquid vitex at 56 drops a day for about 10 days at the end of my last period. I should have had my period last week but it hasn t came. I am sure that I did ovulate about 2.5 weeks ago...I had ovarian pain and I even spotted. I ve taken 6 pregnancy tests in the past week and all are negative. I have been having cramping, off and on for over a week, yet nothing is happening. I was also diagnosed with PCOS due to my testerone levels being higher than they should be. I m not really sure what is going on.
