Can stress couse cramps ? 19 weeks

Hi, I've been really stressed out for about 4 days now. I feel so much anger inside of me towards my bf that I broke up with him. I feel like he isn't even trying to be with me through my pregnancy. We've never been so apart until now. Well, I can't calm this angry feeling that I feel towards him and deep down inside its making me feel, angry, upset, sad, depressed.. Today I woke up feeling out of breath and small light cramps in my lower stomach. Can the stress be causing this? 😕
