What is our advice:
To say the you failed to coveive, you should wait until the end of one year of regular sex. Before one year there is no need for any medical investigation. To help you also, you need to know when to have sex. You need to follow ovulation date. Ovulation date is when the ovary is producing the ovium (egg) and it can be calculated by deducting 14 days from the length of the menstrual cycle. For example if the menstrual cycle is 28 day, the ovulation date is the 14th day. Note: the cycle start from the first day of menses. Also we advice only to do semen analysis for your partner.
