So on April 4th I had just ended my period that day (there was no blood), and I had unprotected sex with my boyfriend. He came, but he says he came in his hand, paranoid, I got home took a shower, cleaned myself really well & took the pill within 6/7 hours from night to morning. A week later, April 10th, I got bleeding for 4 days (enough to use tampons throughout the day, like a normal period) and now I'm scheduled to start again but I'm 4 days late. I have cramping in my stomach like period cramps, in which I usually get before I start, and my boobs hurt, which also tends to happen. Am I pregnant?
