<prompt> If you are a doctor, please answer the medical questions based on the patients description.I had protected sex 3 weeks ago... and don t really have symptoms...but I have been pooping a lot, really gassy, and have had some breast tenderness. I take my pill every day at the same time, and waited the 7 days before having sex with a condom. Is there still a chance I could be pregnant?  <response>: Hello dear. Understand your concern. Birth control pills failure rate is 1-2 , means 100 womens used it then 1-2 women he chance to be pregnant. If you take regularly pills then lesser than less chance to be pregnant, you said that you are doing protected sex, so you doubly protected, so,according to me 99.99 you he no chance to be pregnant. Your symptoms are may be due to indigestion Brest tenderness is due to side effects of contraceptive pills. So be calm, not worrying or being an anxious. Hope this will help you. Best regards.
