Hello, and I hope I can help you today. First of all, I want to reassure you that it commonly can take up to a year from healthy couples to conceive. You are not diagnosed as infertile unless you and your husband have been trying to conceive (which means having unprotected intercourse at least two or three days a week) for at least a year. Folic acid is a B vitamin that does not help you to get pregnant, however it is recommended to take during early pregnancy because it helps prevent birth defects. Siphene, also known as clomiphene citrate, is a fertility medication. It can help induce ovulation in women who are infertile because they do not ovulate. However, if your periods normally come every month, there is no reason to suspect that you are not ovulating. Because you are under the age of 35, I recommend that you and your husband to not take any more fertility medications and try to conceive for another six months on your own. Normally, your most fertile time is between the time your period stops until you start to feel premenstrual symptoms. For most couples, that means having sex every other day from about the seventh day of your cycle until the 23rd to 25th day. If you and your husband have not conceived in another six months, I recommend both of you see fertility specialist, as 50% of the time lack of pregnancy can be a problem with the man s sperm as well. I hope that I was able to adequately answer your question today, and that my advice was helpful, and you and your husband are able to have a baby soon. Best wishes, Dr. Brown
