Thank you for your question. I understand your confusion. It can be really difficult to know why the period was delayed when it never happened before. I would suggest that if you have been trying for less than a year and you both are in good health otherwise, do not take this too much to heart. 95% couples conceive within two years of trying with regular intercourse. Of course if this happens several times please consult a gynaecologist who can help rule out any other problems that may be interfering with you getting pregnant.  Do make sure you are taking folic acid as this vitamin helps the fetus in its neural tract development. You can get it from the pharmacy. Alternatively you can consult your doctor who can prescribe it for you. best wishes
