TMI BUT NEED ANSWERS ASAP PLEASE

I'm 15w with my rainbow baby ❤ I've noticed everytime I pass a bowel movement it's been the same green as the nurture Apps "GREEN". No matter what I ate prior to that it's consistently been green for about 2 weeks. I've also been coughing up a lot of brown phlegm. My next appt isn't for another 2.5 weeks. Should I be alarmed? Is something wrong?
