Missed Period? Help?

I'm now two days late for my period. I've been told by my dr who prescribed me the metro gel as he told me I have BV that it doesn't affect periods. They pg tested me Monday(10/31) and I'm assuming it was negative because they didn't tell me. Since being off my birth control I have had regular periods. A day before, on the day, or day after is when I usually start but not this time. When I was pregnant with my daughter I tested 2 days after missed period and it was negative. I got really emotional on Christmas eve, took a test, and it was positive. Test or wait? I'm so confused. Feeling fuller boob but not sore to the tough. Nausea, extreme fatigue, some cramping.
