Hi, If you take Agnus Castus/Vitex what dose do you take, how long have you been taking for, and what difference have you noticed? Feeling a bit disheartened. I've been taking since cd1 this cycle now cd24 - Holland and Barrettt 1600 mg - 4 tablets a day. Compared to last cycle - no real ewm whereas last cycle at this stage I had lots and had ovulated. So ovulation is going to be later rather than earlier. Spotting for 3 days after period which also didn't happen last cycle. Only negative side effects at the moment. TIA!
