Any mommas further along in their pregnancy have any brown spotting early on and everything turn out to be fine?

Yes, the week my period was supposed to come just when I found out I was pregnant. but my OB said it's fine

I had heavy bleeding with clumps and cramping and my whole first trimester and baby is doing great.

brown spotting is old blood , when its bright red you should be worried but check with your OB just incase

go get checked though

yup yup
