Hi Thanks for writing and i have gone through your question. Having sex during the mentioned time is unlikely to result in pregnancy. More than likely, your ovulation is several days away, decreasing any chances of conceiving during this time. Even though unlikely to get pregnant during her period, it is possible. If you are not planning to be pregnant i would suggest you to use one or the other method of contraception. One of the earliest and simplest way to know that you are pregnant or not, is by using, urine pregnancy test. Most experts advise that you should wait at least one day after your missed period before taking a home pregnancy test, though waiting a week is considered best. This can be tough when you are anxious to find out if you re pregnant, but waiting allows for a higher degree of accuracy when taking the test, as hCG levels rise rapidly in pregnant women. It s best to do the home pregnancy test first thing in the morning, when your urine is most concentrated and hCG levels are highest. So I advice you to perform a test a week after missed period and with morning sample of urine. This test kits are nearly 98% accurate, so reliable. With transvaginal ultrasonography, the diagnosis of pregnancy can be made earlier by 4-5 weeks gestation Yet again, I duly appreciate your query to me, I do hope that you have found something useful to help you and I shall be glad to answer any further apprehensions. Sincerely,
