Am I pregnant?

I am experiencing white discharge, hot flushes, dizziness, headaches when I wake up and what feels like bloating.. My boyfriend and I had sex the day my period finished.. And just to try it out we didn't use protection...(but he only went in once or twice in a row- and stopped as soon as it started to feel good). We did this too see if I was really allergic too latex or if it was something else. But now I'm worried I'm pregnant.
