Hello and welcome, I am Dr Nilajkumar a consultant gynecologist and I will be helping you in your queries. I understand that you have come back for a very short time. Unfortunately the mature egg report remains valid only for a day or two as the egg releases after this and if sexual contact occurs during that time pregnancy is possible. So please check if you had contact during the time the egg was likely to be released [ next 1-2 days after the scan]. I will inform you a little about the female physiology and how pregnancy occurs. Every month a single female egg is produced and released to be fertilised by the male sperm. This occurs on day 14 of the cycle in women with regular cycles but may occur on any day from day 12-18. The egg is alive for only 24-36 hours and after that it is lost. So contact during this narrow time of egg release will result in pregnancy. Rest of the whole month sexual contact will not cause pregnancy. Normally couples have contact 2-3 times a week and in one of the month it happens during ovulation resulting in pregnancy. The day of ovulation can be judged by thinning of cervical mucus, increase in basal body temperature measured by a special thermometer before getting up from bed daily or using ovulation detecting kits. I hope that you understand it now and will be able to plan things accordingly. I am here to provide any more answers that you may need. Best of luck and thanks for using HCM. Have a good day.
