Hello. I'm 16, and my period is late. The only sexual contact I've had since my last period was with my boyfriend's fingers. He fingered me, and gave me an oral, and it was for the first time ever for me. Now, I seriously doubt he had any pre-cum or cum on his fingers before fingering me...

Also, my period is quite irregular, but I've never missed it once.. I guess it should've come somewhere around the 26th-27th, but we're on the 30th of August, and still no period. I've had the usual premenstrual cramps, the acne, and these are my telltale signs, but for now, there's no blood.. Could I be pregnant?
