Okay here is what I found:Grapefruit Juice: There seems to be lots of speculation on this tip. Some women swear it is one of the best tips for getting pregnant and others not so much. There also seems to be some missing data and studies that would either confirm or refute the viability of using grapefruit juice to increase chances of conceiving.
However, grapefruit juice may slow down metabolism of estrogen (estradiol) leading to increased levels in the blood. Estrogen is one of the things indirectly responsible for increased fertile EWCM (egg white cervical mucus) just before and during ovulation among other things such as the development of the endometrial lining which accepts and nourishes the embryo at implantation.
I do know one thing; it can not hurt you. If all it does is help increase your fluid intake for hydration, then good enough. It may also increase the quantity and quality of your mucus and increase the thickness and nourishing qualities of the uterine lining, and so on. Try it, it just might work for you. Plus, when you drink it, it can help with pH balance of your vagina. pH balance is necessary for the survival of sperm.
You should be sure to get the all-natural, not-from-concentrate form and drink about 4 to 5 glasses a day for about a week before you expect to ovulate.
I would also like to point out that the main ingredient in those hollywood diets are juices like this so it may cause you to go number two more often
