After missed period: 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

Hello. : Hello. Pregnancy symptoms can begin at the time you first miss your period. They can include some of the symptoms you are referring to: breast tenderness and swelling, widening girth and nausea or vomiting. Additional symptoms can include: lack of period, moodiness, increased frequency of urinating, headaches, insomnia, feeling tired, passing gas, just to mention a few. If you took the urine pregnancy test before you missed your period it would probably not be positive yet. Most women take the test at the time they miss their period. Sometimes, even if a woman is pregnant, the test shows a negative because the HCG titer is too low to trigger the test, i that case, it can be retaken a week or even earlier. Take care. ...Read more
