Too soon to test: 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. ...Read more

May repeat in a week: Today's home pregnancy tests are very accurate and not affected by foods, herbs, common illnesses, sexually transmitted diseases, vaginal spotting, or medications. A test gives a reliable result 3 weeks after sex (or when conception might have happened) or 1 week after missing a period. If done sooner, a negative result may be due to testing too early, such as less than 2 weeks after conception. ...Read more

3 consecutive missed periods, several negative pregnancy tests. Take Loestrin 1.5/30 reliably. Pregnancy tests inaccurate? Should I get a blood test?

Not Uncommon: There are some women who may eventually stop menstruating on OCPs, especially if they have been on them for a period of time. Or, if they have some conditions like polycystic ovarian syndrome. If 3 pregnancy tests are negative, you are not likely to be pregnant. As long as you take your BCP as directed, there should be nothing to worry about. ...Read more

4 months since last depo, been having symptoms of pregnancy, is it my hormones or should I go get a blood test from the doctor?

The only way: To truely differentiate those symptoms is to do a serum or urine HCG test.Breast tenderness and swelling, cramping, and and many other early pregnancy symptoms are the same as period symptoms. Doc can do a blood test that is the most sensitive. Don't forget that depo can help protect you from pregnancy, but it doesn't do anything for std's--which frequently are forever for women. ...Read more
