I experienced "spotting" during my pregnancy. It was due to being dehydrated, sex, a UTI or physically doing to much house chores. As long as it is not associated with nausea, vomiting, fever or cramping then a little spotting should not be a problem unless you have other medical problems.
My Dr said bleeding was not good in pregnancy. So no bleeding is a great thing!
Hope so i havent had any bleeding eather 10 weeks
