Hi. I don't have a very regular period but, I do believe that I was suppose to start at the end of September early October. I have not started yet and I have been very stressed thinking I'm pregnant. I have all of my PMS symptoms. Sore breasts, nipples, cramps, my face was breaking out, and earlier today I had some clear nipple discharge. I have never had that before. I also had mood swings. I don't ha any nausea. I did have some brown vaginal discharge around the end of September. My partner and I did have sexual intercourse around the middle of September. He did not ejaculate inside my vagina. However, we did not use a condom. But the intercourse was maybe for 10 seconds.
