I missed my pills two separate times maybe three but no more than that max. The two times I forgot I doubled up. I have been having a sore throat and headache but it has only been one week since this unprotected sex happened and I really don't believe that you can tell symptoms that quickly. I have not had sex in the last seven days like requested. i am just wondering if there is any way i could be pregnant. I am on Yasmin and do two 21 day cycles concurrently. Have been on birth control for about 9 years.
