Help ols

It's been exactly two weeks since I had unprotected sex and missed pills. I just took my last sugar pill and I still have not gotten my period yet. I usually bleed a lot or at least spot but all i've had is clear discharge and now I just passed this. i've gained weight and my boobs are super swollen, and I've had some mild cramps. Is it too early to take a test? I'm scared i'm pregnant
