Its been 13 days since ive had protected sex should i take a pregnancy test if i used a condom when i had sex?

Repeat post, read my other answer. Take the test a week after you miss a period.

Conception occurs within day or so of the sex. It takes about 3 weeks for the embryo to make enough HCG for 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.
