hello! My gf have been late for 4 days and still do not have any sign of period. What could it be? We did not have sex and only did mutual masturbation (hj & bj only). We actually did have genital contact WITH condom but since then she already had 2 normal period.(two months back)
She is suppose to get her period last 4 days considering she is regular 28-29 days. As far as her concern, she did not miss nor have late period before. She was stressed by her exam last 2 weeks, could this be one of the factor?
