Implantaion bleeding only occurs in about 10% of women. If the blood test was negative, you probably aren't pregnant. And since you haven't had a peiod, you haven't ovulated. AND let's say you ovulated on dec. 26th, then you are 3 weeks pregnant.
Just to ease your mind, provera doesn't harm the baby. As long as you don't take a high dose.
