Hi doctors i had protected sex two days after my period, it's two weeks since the time passed my breasts are extremely sore they are painful took two pregnancy tests both on day 14 after sex and day 16 after sex both negative can these be accurate?

You'll need to retake the test a week to ten days after a missed period. Before that time the result may not be accurate.

You tested too early and a negative pregnancy test at this time does not rule out 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,
