How Long Should I Take Vitex for Fertility?

How Long Should I Take Vitex for Fertility?


Hi Hethir, I have been taking vitex for 3 weeks now and I am on day 35 of my cycle, am I supposed to stop taking the vitex on a certain day so my period will start. I did hpt it was negative.


There are two schools of thought on how to take Vitex. Most herbalists say that you can take it every day for up to 18 months, unless you get pregnant. Some other sources say to take it for two weeks before ovulation than stop, just in case you are pregnant.

With my clients I usually suggest taking it all month long.

Vitex does not contain any hormones in it yet acts by balancing the hormonal system. I personally take it daily (luteal phase imbalance); when I find out that I am pregnant I will stop.

As for your cycle being 35 days, if it was not normally that long; it may be a sign that the vitex is working to balance things out. Sometimes when the body is healing, it will seem a little more out of whack for a very short time and then comes back into balance.

Vitex and progesterone can be taken at the same time (remember progesterone is taken only after ovulation until menses or if you become pregnant, for at least the first three months.)

  1. hello, I am trying to get pregnant. I have a 7 years old, I was on birth control for 4 years the IUD cooper. I got out of it a year ago and since then ive been trying to conceive but no result. my period comes pretty much the same day every month. I have a 30 day cycle I will say. I don’t really know my luteal time frame. I am 26 years old and don’t have heavy bleeding or experience difficult PMS. Usually light cramps few days before. so I am considering vitex. My period comes tomorrow and I was going to start day 1. how many times a day do I take vitex?

  2. Are there any harms in taking Vitex if you are pregnant and don’t know yet? Or it is fine to continue to take until you find out?
