Are you still taking your Loestrin
regularly? Also you did not mention your age and whether you have any other problems like diabetes
or blood pressure. If all these are normal, and you are below 40 year age, and you are having bleeding after every sexual intercourse, I suggest get a transvaginal pelvic sonography
done to assess the uterus. If all is normal even then, may be you just need to upgrade to another contraceptive
Do give us feedback so we can help better.
Take care and regards,
