If i did hcg beta serum test after 10 days from foreplay that ejaculation occurred on thighs and breast it can be given me accurate result? i done it today and my result was 1.20, last period was 31/7 usually my period cycle around 28 and 30 days?

You tested too early. What you described is not likely to result in pregnancy. If you miss your period by 4-5 days, do a home pregnancy test. If the result is negative repeat the test 4-5 days later unless you get a period by then. Use first morning urine and follow the instructions carefully. Wish you good health! If you do not wish to be pregnant, use contraception all the time, every time.

Ejaculation confined to thighs and breast will not cause pregnancy
