Normally my period is 7 days and heavy. For the past two or three times it has been lighter and shorter - like 5 days. Also I got it either late and I just recently got it 10 days early. The only concern I can think of is that my boyfriend fingered ke and he may have had sperm on his hand, but it wasn't directly "fresh". I know it's a low possibility especially because I have gotten my period but it just doesn't seem the same. Also I have been very hungry lately.
