So hoping I'm finally pregnant??

Here lately I've been feeling a little weird. I didn't have a period for a month but I went off depo in April and have been irregular a little but never missed one. Saturday morning I had some spotting like and I thought I was going to start but I didn't . It lasted maybe a hour-2. But I've had mild cramps all week on and off! And an upset sore stomach. Also I've been craving and eating foods that I didn't really like or haven't liked for a long time before. I've also had a low temp the past couple days in the evenings. And have hot flashes on and off.. Any suggestions anyone ? ?
