My cycle is usually 28-30 days very exact. Last period was February 27-March1 and next expected is 27-30. I had unprotected sex the 11th of this month he did not finish and I took plan b 30 minutes after it happened. My ovulation date was the 13th. The 19th we had sex again with a condom and noticed there was brown thick discharge. What is this from?? We had unprotected sex again that night for only 10 seconds he did not finish and I got plan b about 8-9 hours later. Usually I get tender breasts and cramping before period and today that is happening. What is happening please help
