Pregnant and arguing

So I took some tests the other day & turns out I may be pregnant. Due to the fact that I tested on Christmas eve I have to wait until Monday to call and schedule an appointment, I took these tests the other day that estimates how far along I am. They came back I am about 6 weeks, today I over sleep, my hubby made me breakfast but I was so sleepy and I felt awful this morning and couldn't even eat eggs, anyways me and my hubby get into it really bad I cried for 2 hours  and now I'm so scared that I may miscarry bc of our fight and me stressing over being stressed. I really need some homely advise. I know this is a lot but I wanted yall to kind of be on my page. Thanks
