2 weeks ago, i had sex with my boyfriend more than a few times in that and i was due to get my period. On june 27 i got my period, which was surprising not heavy. usually it last 5-6 days and quite heavy the first few days. well this period was here sunday, gone tuesday night pretty. By monday night, it was light pinkish brown color and then late tuesday night, wednesday morning it was gone. What im wondering is, what are my chances of getting pregnant in such a short time frame?
