Advice needed

So last month, I had gotten my period five days early. My periods are always long, extremely heavy. This period wasn't as heavy it was seven days but the last three days were light and brown. After my period, I am still bloated, my breast aren't sore but are still veiny and a little fuller than usual, extreme fatigue, and randomly nauseous through out the day. Should I get a blood test from my dr. Just in case I could possibly be pregnant? Or not bother and assume it's just my crazy..also on top of it all I have a yeast infection now! I thought it could be my soap but I read that you can get one from pregnancy. Lol I'm so crazy.
