Early pregnancy symptoms?

So a few days Ago I started having tender boobs. They aren't painful, but they're tender to the touch, but not too bad. The last time I was pregnant, they hurt so bad even taking showers hurt. But the last couple of days my lower back has started to hurt and I've been having cramps. My nose would randomly start to run, which I thought I was getting a cold but I'm not cause it would randomly stop and start again throughout the day. Also I have been having crazy heat flashes, I have never had them like this before. As of lately I have also had to get up in the middle of the night to use the rest room. Just once though.. Which I usually don't, since I tend to always use the bathroom before I go to bed...My period should be due next week, & i don't think I am pregnant, but DH & I have been trying. My last pregnant resulted in a miscarriage so I'm not sure what to expect. Did y'all have any early symptoms that let you know right away? Plan on taking a test next week, just curious.
