Hi. Welcome to HCM forum. HPT if done early it may show negative results. U have not mentioned since when u have missed your periods. Blood test
shows positive result before a urine pregnancy
test. HPT may take more than week sometimes to show any positive results. Heaviness in your uterus
is not related to pregnancy, even if pregnant it will take time for u to feel heaviness. Dont be very anxious and trust your doctor, wait for the results. If it is negative then it is better to find the exact problem in u or your husband. It needs some examination for your high temperature. Eat nutritious food and also take tab ovacare 1 daily in afternoon after food, it helps in ovulation. But please do consult a gynecologist. All the best.
