unprotected sex

Me and my husband had unprotected sex, as newlyweds we wanted to have that "bond" if you know what I mean... he came inside of me and he and I both don't want a baby just yet... I want to go and get emergency contraception but they said they do not work in overweight women. He is in the marines and I am not on his insurance yet so I can't get Ella or a IUD... Also I do not ovulate until the end of every month and my period is suppose to start at the end of this week or the next.. should I just risk it and get the plan B or the my way pill? Because I this point I really don't have another option.
