Hi, I m 18 years old. I ve had sex for the 2nd time in about a year. It was unprotected, but he pulled out. I took the Plan B (one-step) a day after. I have been having funny weird feelings in my pelvic area, tender beasts, irritability, and headaches, and I ve also noticed myself urinating more. My period has been irregular since I ve turned 18, but according to last month, it should come in about a week or two. I also noticed for the past few months and since my irregularity has started, that I have been getting faint hot flashes. It has only been five days since intercourse could this mean I am pregnant?
