I'm 5 weeks and 2 days. A few days ago we had sex then I finished in the shower.. i know stupid idea..

Well now I think I got BV. I've read up in it...I'm mostly ichy some pain and some redness, no discharge or smell. At this point I dont have health insurance. Just for a few months. I cant afford to go see a doctor right now. Anyone have any tips for me. Please and thanx
