My last period was June 23-26th. On the 26th I started taking birth control pills and was on them for maybe a week I missed my pill on June 2nd and that night had unprotected sex and let my boyfriend finish in me. I left the next day for a trip and honestly haven't taken my birth control since I've been out of town I forgot it since I've been with family. I was due to start ovulating July 7th But instead on the 5th on through the 8th I had bleeding. At first it was dark brown spotting then it was a light flow between dark red and brown to dark brown. I'm not sure if it's the birth control, implantation, or anything else? Any thoughts???
