I've done some research on this and apparently ovulation tests will come out positive if you are pregnant. As i understand it, ovulation tests pick up LH and HCG alike -- they don't differentiate. Pregnancy tests, however, only pick up HCG. posted 03/19/2008 by a BabyCenter Member.
Step 1. Preheat your oven to 325 degrees Fahrenheit for a pot roast from the round; 425 degrees for a pot roast from the chuck; and 350 degrees for a pot roast from the rib. The weight and type of roast determines the cooking time; you should cook a roast until its internal temperature is between 135 and 150 degrees F.For instance, a 2- to 3-lb. rump roast cooks for 1 Â½ to 2 hours to medium-rare doneness, the Cattlemen's Beef Board and National Cattlemen's Beef Association website advises.tep 4. Remove the pot roast from the oven when it is 5 to 10 degrees below the recommended final internal temperature. Cover the roasting pan loosely with a tent of aluminum foil and let the roast stand for 15 to 20 minutes. The internal temperature of the roast will rise another 5 to 10 degrees.
If you cook chuck roast long enough, it will be very tender and delicious. Many folks tend to take it out of the oven too soon, resulting in a tough piece of meat. You really need about 1 hour of cooking per pound of chuck roast.
