Feeling anxious

So I'm 16 weeks I have had by far the most stressful pregnancy ever I had bleeds n I have placenta previa anyways tonight was a disaster got into a huge fight with my hubby n he stormed out packed a suitcase n I cried n cried n cried n just was amiserable mess for hours now I'm feeling very anxious that something might be wrong with the baby! It's been weeks since my last checkup n this is driving me nuts! Can stress cause a baby to die and if the baby would die would i bleed? Ugh somebody calm my fears
