###Human: Is it normal to have an increased hCG after 48 hours? ###Assistant: Hi. I can understand your concern. According to your description, the possibilities are:  You are pregnant which is indicated by urine and blood tests. Now, we have to confirm whether the pregnancy is in uterus or not. Usually blood levels of beta hCG should double in 48 hours. But that did not happen in your case. Now, we have to rule out the possibilities like abortion or ectopic pregnancy. For this, please undergo ultrasound once which will help in ruling out ectopic pregnancy. Take Progesterone supplements to prevent abortion. And repeat beta hCG levels again after 48 hours, this will help in confirming the site and nature of pregnancy. Take care. Ultrasound, repeat beta hCG levels after 48 hours. Ectopic or abortion. Progesterone supplements.
