 [ Symptoms ] can i be pregnant my last period was on 10<negative_smiley>12 my boyfriend ejaculated in me on 101712 now my period did not come my period was suppose to come on 1122012 but i am late i have always been regular never been late in my life [ Disease ] any time you are not using birth control it is possible to get pregnant it is pretty much that simple ok maybe not granted there are some days when you are much more fertile than others because you are ovulating or on the verge of ovulating assuming your period started on 108 the date of 1017 would be right around your  fertile window  so yes you could possibly be pregnant keep in mind fertility calculators like the one i linked to above are not foolproof the ovaries do not consult a calendar before popping out an egg so you could possibly ovulate before a calendar says you are fertile    or after if your period was due 112 you certainly could take an over the counter pregnancy test now to see if you are pregnant or not i wish you the result you desire
