I might be pregnant and I'm scared HELP!!!

So I'm 22 I had unprotected sex a month ago I took plan b the next day (August 28th) and then I got really sick with a cold for a week and took NyQuil. So my period came on time about 2 weeks ago and it only lasts 6 days but now it hasn't stopped for 2 weeks and I'm still on it. I didn't think much of it bc someone said it was stressed (roommate died) and not to worry but I took a pregnancy test today and it said I was pregnant. I have no doctor and no insurance. The hospital won't do anything and are planned parenthood is closed. Idk what to do. Or if I'm pregnant or its stress or if this is even normal if I am pregnant. Any suggestions will help
