HELP NEEDED

I just got out of an abusive relationship a little over a month ago and I haven't had sex since about 2 weeks before we broke up. I'm 17 and I missed my period 25 days ago, I haven't been worried about being pregnant until a week ago because it's been irregular before but never this late. I ALWAYS used condoms and we always made sure to check during and after for any tears or leakage. Could I still be pregnant? What symptoms should I look for? I can't go to the doctor, my parents can't know until I'm sure. I'll be getting a test later this week. I made a post about a week ago but only one person responded. I have been really stressed out, could that be it?
