Std or ib

Lexi
This is hard to talk about but I need help. I was rapped on New Year's <a href="https://play.google.com/store/apps/details?id=com.glow.android.eve">Eve</a> by a guy I do not know. I'm scared he might have had an std. But also I had sex with my bf prior to this on my fertile window and it's five data before I'm suppose to start my period and I wiped and got this but when I wiped again nothing. No one will help me. I have been nauseous and constipated with slight sore breasts and I am also very very tired. Please help.
