Yesterday my fiancÚ and I had dry butt sex. Ive ever had vaginal sex before and he did not ejaculate. There was also no precum because he had precummed earlier. I am a afraid that he could have precummed a second time although he said there was nothing, and a little dripped down into my vagina. I have sore boobs since yesterday and now I'm urinating frequently. I'm supposed to get my period in 9 days. Can it be I'm pregnant? What are the chances? Is this PMS and I'm doing it in my mind. Please help.
