Symptoms experienced before knowing you are pregnant

I slept A LOT. Every evening when I get home from work, I would feel really exhausted and my husband noticed that for a good two weeks before we tested positive, I would fall asleep as soon as I sat on the sofa in the evening. Had strange vivid dreams that didn't make sense. Just super tired and out of the blue one day, I just thought hey maybe I could be pregnant. It was strange but a fleeting thought that later turned out true.
