I've been delayed for 12 days now. I took a pregnancy test twice yesterday and they were both negative. I'm just wondering what are my chances of being pregnant? I was supposed to have my period on sept. 13 but me and my boyfriend had contact the day before that. We used protection but before we did, he put it in without one for like a quick 3 minutes. I really need your help because I don't know what to do. I'm experiencing nothing out of the ordinary. Just my normal pre-mens symptoms but without the menstruation. I have been under a lot of stress lately and loss 10 pounds in two weeks. Can that be enough to cause a delay? PLEASE HELP.
