I have very irregular periods. Would a pregnancy test 21 days after sex be accurate? I used early response. Last period was July 25.

Too soon to test. If you have a positive test at 21 days, it is reliable, but it is really too early to test, as home urine tests are usually reliable at 1 week after missed menses, which are usually 28-30 days for many women. I would recommend testing at 5 weeks or 35 days after onset of last menses. A blood test can be done which is very sensitive and would be reliable 7-12 days after conception. Read more...

I have extremely irregular periods. How many days after intercourse will a pregnancy test be accurate?

Three weeks. Conception, as defined by the generation of a fertilized ovum, occurs within day or so of the sex. However, it takes about 2-3 weeks for the embryo to make enough HCG to produce a positive pregnancy test. Blood test may be done a day after a missed period. Home pregnancy tests should be done 4-5 days after the missed period. If the result is negative repeat the test in 4-5 days. Use first morning urine and follow instructions for the test carefully. If you do not wish to be pregnant, use contraception all the time, every time. You may consider implanted contraceptive, or IUD. Practice safe sex. Get HPV vaccine. Read more...
