Light brown spotting again!!!

Em

So at 4 weeks 2 days I had light brown spotting for three days then stopped. I had to get my hcg check and all was well with that, and was scheduled for a ultrasound at 5wks 4 days just to make sure baby was in the right spot! Ultrasound was perfect, finally I could breath and not worry anymore!!!

Buttttt then yesterday (exactly 6 weeks pregnant) happened. I got home from work went to the bathroom and the dreaded brown spotting was back!!! Today it seems to be almost gone.

Anyone have on and off spotting through their 1st trimester? This is my fifth pregnancy, no previous losses and this has never happened to me with any of the other ones!
