I have been a bit regular 27-31. But for a year plus now is between 29 and 31. I have been on vitex a month plus. First month my cycle was 29days and this month am 3days late(done test BFN). Am actually started taking vitex becos of high prolactin. When I take carbergoline it stops and if I stop taking it increases. Pls ur advice and experience is highly appreciated.
