Late period! Could I be pregnant?!


Ok.. I'm spilling the beans, me and my boyfriend have sex without protection.. he has came inside multiple times this month and the previous. I am a week late with my period, could I be pregnant? I know this may sound like a silly question, last month I was late within 3 days.. but it has officially marked day 7. Without it coming. I do have to admit. When we had sex yesterday I did have some pretty bad cramps and I bled a little. I thought he started it off for me so obviously I was. Happy! The next day, I checked.. and it was nothing. No spotting or anything. It's like it never happened.. so I'm a bit worried that I may be . HELP!!
