My period is already 9 days late and i'm really scared about that.  Last time i had it on 20th of May... me and my boyfriend never had unprotected sex. This month we only did some oral and fingering. We are pretty carefull anyway. I already did a test 2 days ago and another one today. Both of them in the morning and came out negative. I'm so stressed about that... can you help me please?
