On feb 25th 07 my bofriend and i had sex twice. The 1st time we used protection and the sec none and he didn't pull out. I eat normal and excersise like i usually do.

There is a possiblity you are pregnant. However, your dates can vary especially with stress.

If you find that you do not get your period within the next 10 days or so, it would be in your best interest to take a HPT using first morning urine.
