Hello, Im new here and i have a burning question. I had unprotected sex on 2017/07/31 and my periods stared on 2017/08/01 and lasted 5 days (ended- 2017/08/05). So since yesterday i have been seeing a dark brown discharge (now is just drown) on my panties liner and when i wipe. My periods are only due to start on 2017/08/29. I dont know what it all means and it scares me. thank you for reading this. i hope to hear from you soon.
