Last night I had unprotected sex. Although I have been on birth control for 7 years and rarely miss a pill, he still pulled out. I woke up this morning to light spotting and realized I had forgotten to take my pill. I went ahead and took my missed pill about 11 hours late. Is there a greater risk I could become pregnant and should I take Plan B? I have tried calling my Doctor but she hasn't gotten back to me. Thanks in advance.
