grapefruit juice/robitussin/preseed

Can someone tell me how much and when to take the grapefruit and robitussin please.  Also trying preseed.  After using preseed, how much time do I have for intimacy before I have to reapply again.

um with the preseed try not to use so much....they say its sperm friendly but I believe too much can do more damage than good!!! i used pressed and I only used a dab like a lil and just rub it in my vaginal but some women use half an applicator... one dose is good and they say use it before 30 mins!!! goood luck

I started using the Robitussin the day after my last pill up until I got a positive OPK.  It was for about 8 days total.

Hi hun the robitussin you take as soon as your period is finished and stop as soon as you ovulate,take a spoonful morning and night.Then drink ordinary yellow grapefruit juice a glass daily,and again start when period finishes until you ovulate.Another good thing to take is vitamin b6.All these taken together have helped me so much.I am on clomid and it can dry up CM in some women so i didnt want to take any chances.I also did research on it all.I have noticed my CM the past few months and i never did before so it really has made a big difference.I hope i was helpful if you need any more info just ask anytime honey SSBD xx p.s take vitamin b6 all through your cycle.

My understanding is 2 teaspoons of Robitussin three times per day, followed by a full glass of water. Starting, as mentioned the day after your period ends through to ovulation.
