Hello dear, I understand your concern. The utrogestan is a natural micronised progesterone and is prescribed in cases of threatened miscarriage or past history of miscarriage or any dull pain in pregnancy etc. It can be taken by two routes orally or vaginally. Usually it is said that the absorption will be better and sideeffects will be less with vaginal route. But studies done with utrogestan has similar effectiveness with both oral and vaginal route. But nothing like it s going to harm the baby by taking through oral route. So relax.Avoid stress.Avoid physical strain and intercourse. Take good rest and healthy nutritional diet. Nothing to worry. Hope this helps. Best regards...Dr.Srilatha
