Pain in my abdomen

I've had cramp like feeling on my lower abdomen for a month now and last month I had the lightest period with no cramps when I usually have a very heavy flow with bad cramps. I'm not sure if it was due to different foods since I went to a different country but I just have not been feeling very well since. And I also feel bloated all the time. I just need some answers😓 my next period is in a week. If anyone can help that would be helpful☺️
