Need poop advice

I’m 32. I have a high stress job, had several significant deaths in my family recently, moved away from home for the first time and just got engaged. You can say there are lots of reasons to have stress. My problem is, it’s affecting my cycle and my poop schedule. I’ll go days without going to bathroom. I’ve tried probiotics and magnesium. I’ll admit I’m not exercising regularly like I used to because my schedule just doesn’t allow it. I’m constantly bloated and tired and miserable. Any advice???
