My periods are always on time and the same flow and the same duration of time(being 5-6 days). My period started last thursday, and on saturday i had unprotected sex where my boyfriend ejaculated inside of me. Then still even the next day i had not bled anymore, and even a day(monday) later there was still no blood. Then i spotted a light pinkish fluid a tiny bit on monday night. Then it stopped again and now today, being wednesday i spotted a bit but thats it. I feel a bit different, any idea whats going on?
