So, we have booked some time away just the two of us (29th May- 1st June) and this is right on top of my expected ovulation! I am taking Vitex af - cd13. Because we are going away for a romantic break it will be very difficult for me to make an excuse to not dtd as we are at the moment doing e4d.... My question is: if we dtd a few times during the time away will that cancel out the Vitex and make it too boy friendly? Is there anything else I can do to combat this?
