I didnt take B6 but it took on our 5th cycle it finally reached 11 days, 6th was 11, 7 was 13, got pregnant on the 8. My 4th cycle was only 6 days long. It took my body sometime to get back to normal. The biggest thing for me was to not think about it. We actually got pregnant and the month we stopped. Hope someone can help that took B6!! good luck
