Sign of a miscarriage possibly??? Help!

Bianca

So I missed my thyroid medications due to bad circumstances for a whole day. I took them as soon as I was able. I have been having some bad aches occasionally and at one point it was a severe cramp. Then I went to the bathroom and I thought I was getting brown discharge the color before heavy bleeding. But I think the bathroom lighting was off because now it looks like a dark yellow discharge. No smell or anything. Has this happened to anyone else? I was so freaked I was losing the baby. I still haven't gone for my confirmation ultrasound and I debated going to the ER just to be sure. I was also really dehydrated and without food for some of that 24 hours and extremely stressed.
