Hello, Thanks for posting your query. Loestrin is female sex steroid, that has been started by your doctor to improve the vaginal epithelium health. This medicine should be started after a per speculum examination of the vagina for any serious cause behind the bleeding. You should take the whole strip of tablets and then take a holiday of one week before restarting the medicine. Stopping for two days in a row may not protect you from bleeding. You should get assessed by a local gynecologist. I hope this answers your query. In case you have any follow up queries or doubts, you can forward them for me, and I shall be glad to help you. Please accept my answer in case you do not have further queries. Wishing you good health.
