Hello dear, I understand your concern. In my opinion meprate is not suggested to take during pregnancy. If the lady is on meprate and pregnancy is accidentally detected then the meprate is stopped. Meprate is associated with genetic abnormalities in fetus .But ofcourse there is no clear indication of damage caused by it. Your doctor might have prescribed only after the pregnancy is 100% ruled out. If you were pregnant the urine pregnancy test would have been positive. If you still want to confirm blood BHCG test can be done to check for pregnancy. But any doctor prescribes it only after confirming the absence of pregnancy. So relax. Hope this helps. Best regards....Dr.Srilatha
