My wife and i been trying for a baby...we worked hard during her ovulation and she's had food aversions and she's now spotting blood that seems a little different from her usual periods and this time the blood has no funny odour.. could she be preg?

In medicine we are taught to never say never. Here if these symptoms are from the hormones of pregnancy, they would be at a high enough level to turn a pregnancy test positive. Do the test. Such symptoms are vague and may be unrelated.

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.
