Possible Early Miscarriage?

My fiancé and I had a broken condom early last month and I was experiencing several pregnancy symptoms, but I decided to wait to take the test until after I had missed my period. Instead, I had a really mucousy period and I thought I saw a couple pieces of what looked like skin? I'm still experiencing several pregnant symptoms including nauseau, which I just started experiencing yesterday. I would be about 5 weeks if I was pregnant. I don't want to convince myself that I am pregnant if I'm not, but I don't want to ignore if I am. Does anyone have any advice or thoughts? Prayers for my sanity would be great!
