Hallow Dear, How long you should wait giving the fair trial for natural conception depends upon the age of the couple, which you have not mentioned. Though you are married for 1 year and 4 months, you are sincerely trying for pregnancy for last 6 months only. If you are above 25 years of age, it is the time now that you start investigating both of you. You may not carry all the investigations straight a way. Initially try to find evidence of your egg release. Though in the market home kits are available, I would advise you initially to get the evidence by ultrasonography. This will ensure whether you are ovulating or not; and if you are ovulating, it will inform you the day of your ovulation (egg release). Egg has a life of 24 hours while the sperms are active for 24 hours. Hence, a period of about one week around the day of ovulation is fertile window. Then get husband s semen examination done for the quality and quantity of the sperms. If both these investigation reports are within normal range, try to plan your intercourse at and around the day of ovulation. Lying on your back for about an hour after the intercourse is advisable. After intercourse, some amount of semen does flow out passively, it is hardly 10% to 20% of the total semen; so not an issue. To minimise this flow of semen, the penis should not be withdrawn while it is hard. Let it slip out of vagina passively when it is placid. If you fail to conceive even after six months fair trial like this, get Hysterosalpingography and Laparoscopy done to find out the condition and patency of the tubes and uterus. However, if you are above 30 years of your age, get both of you investigated completely without delay. Report then to your Infertility consultant for further advice.
