Brief Answer: Immediate protection if your previous cycles are.. Detailed Answer: Hi, Microgynon is supposed to protect you against pregnancy immediately and there is no need for addition precautions. However the only exception lies when your previous menstrual cycles are shorter say less than 23 or 24 days. If your previous cycles were irregular and shorter I would suggest you to use morning after pill that are available over the counter. These pills are known to work almost 99 out of 100 times. Failure rates are exceedingly low. Hope I have answered your question. Let me know if you need clarifications. Regards

Brief Answer: Possible infection... Detailed Answer: Microgynon protects very well against infection, but it definitely doesn't act against infections. With every unprotected intercourse, chances of infections are likely. Increased urination and blood most likely seem to be infection to me. Routine urine examination is required to confirm presence of infection. At this moment my suggestions to you are: 1. Drink plenty of fluids. 2. Try cranberries - juice or cranberry pills. 3. Maintain good hygiene. 4. Abstain from sexual intercourse. You should visit a doctor and get the urine tested if symptoms persist for more than couple of days or if you start having fever. As far as pregnancy, I would not be concerned about it. This pill offers enough protection against it. Even if it didn't, your are not close to the fertile days when pregnancy is likely. Hope I have answered your questions. Regards
