### input:
I am on birth control (pill), and had unprotected sex. Heres the thing, I was only on the pill for 7 days and for 7 of those days I was taking Amoxicillin, and forgot my pill on the 8th day. My period was due 6 days before I had sex. I am a day late and had spotting of a redish/brown color today. It has stopped completly now. Could I be pregnant?

### output:

Hallow Dear, There are few issues in your query which need clarification to you. Let me explain one by one.1. If you miss just one pill during whole cycle of birth control pills, the effect of the pills remains, and they do not fail. So the chances of pregnancy are almost nil due to missing of one pill.2. On 6th day of the menstrual cycle, there is no egg present for the fertilization. The egg is released (ovulation) 14 days prior to next expected menses. The egg has life of 24 hours while the sperms are active for 72 hours. Hence, a period of about one week around the day of ovulation is the fertile period. Unprotected sexual intercourse in the fertile period is most likely to result in pregnancy. Your intercourse was far away from fertile period. 3. There only one method by which you can reliably detect pregnancy just one day after missing period; and that is Beta Chat Doctor test. This test can diagnose pregnancy even few days before missing period. The other home pregnancy tests which are performed on urine are reliable 8-10 days after missed period. Earlier, they may give false negative results. 4. If you had diarrhea after Doxycycline (which is a common side effect of these antibiotics), there is a chance that pills could have got expelled before complete absorption and then the pills may fail to offer protection from the pregnancy. I hope this helps you.
