He ejaculated inside me about 3 more times, and we kept having unprotected sex until wenesday 20th when I started getting a weird smell down there and decided to take plan b. But on monday 25th I started spotting a little bit and I was supposed to get my period on wenesday 20th. I still havnt gotten my period but I've been spotting light and dark blood with dark brown discharge. Its been 2 weeks already. Help.....
