Could be.....?

Do I haven't been on here in a awhile and just over the last couple of weeks I've been having back pains and feel nauseous every time I wake up and sometime if I get up too fast. I'm 8 days late. I took a test on my 4th day and it came out negative. I read that if I wait for another 2 weeks I'll know for sure if I'm pregnant or not unless my period shows up before then. I don't want to get too excited. People say usually your breadt get tender but that hasn't happened my fingers have swollen up a lot like I can't even wear my wedding rings. Any advice?
