I have had intercorse with my boyfriend after a day at the beach. Two days later I got my period it was on the day it was supposed to come. I saw something weird, the first day my period was pinkish and very little. I was scared I could be pregnant. (I had cramps like two days before and the 1st and 2nd day)  but then I also noticed a weird sweet smell. The second day the flow of my period was heavier and darker, but there was still that weird smell. Im on day 3 of my period and I still can smell it. I will visit a gynecologist once my period is gone, but can anyone tell me if it is normal? I really am scared this has never happened to me before I am a very clean person. What could it be?
