I'm 17 and me and my boyfriend had unprotected sex about a month ago. It was on the last day, then on the day after of my period. And I let him bust in me. Stupidly. That same weekend I got my first depo shot too. And now I'm having a lot of symptoms.. but pregnancy and the depo shot have the same symptoms. Is there any way I can be sure I'm not pregnant without a taking a test?

There is NO way to know without a test, unless you wait several months.

Anyway, which is it ?
