Could i be pregnant, due on any day now?

the last day of my last period was 31/12/08, i had unprotected on that day and two days later. i did take a morning after pill(on the third day). at this time i was not on any contraceptive as my ex partner had a vasectomy. after taking the morning after pill i had light spotting for a day. i went to my doctor and got put onto the contraceptive pill, i was told to use condoms for 7 days so the pill could work properly. during this 7 days a condom split. i am due on my period any day as i have taken the last pill in my packet this morning. i have been feeling very tierd, sick and needing to pee alot. i know this is confusing, but can any one help? xx
