Hi, I just have a question and hopefully someone can help. I keep track of my cycle on a calendar and it's always on time. However, I missed my period this week. I had all the symptoms leading up to it. I did have unprotected sex about a month ago. I'm 3 days late and I have brown discharge that's like mucus. My boobs feel like they weigh ten pounds, I'm extremely tired, and I have been craving different foods. Should I take a pregnancy test?
