Had unprotected sex on eve of ovulation and on the of ovulation as well..1 week left for my period but feeling bloating,having discharge and back pain?

Unclear question: If you are wondering if you are pregnant, it is too soon to tell. Conception, as defined by the generation of a fertilized ovum, occurs within day or so of the sex. However, it takes about 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.
