Am i pregnant??

kaitlyn

on about cycle day 18/19 I had period sex because it was ultra light. my periods usually only las about 4 days. for the last two days I've been sick as hell. a constant migraine, runny nose and for the first day, a sore throat. I'm most worried about the cramps I've been having around my hip on the right side and being so unbearably tired. is it too early to be showing symptoms of pregnancy or am I just sick??
