Question- help please.

Okay so this might sound stupid! And I'm sorry if it does. I'm a ftm, second pregnancy, first ended in an early miscariage. I'm currently 15w6d with twins. My SO and myself had a huge fight which in turn caused me a great deal of stress... I'm now cramping... Should I be worried? I haven't had cramps for a week or so... It isn't overly painful, hardly at all more just uncomfortable. Do I need to worry? Should I go up to emerge and get checked? Opinions and reassurance please!
