Spotting and discharge

Needing some advice. Have had brown discharge on and off since Thursday. It’s not enough to fill a pad and is only noticeable when I wipe. This morning it was totally gone and then when I just went to the bathroom it was definitely a little more brown mixed with maybe blood. Still no clots, no cramps, and it doesn’t even show on my panty liner. Just wondering if I should go to the ER as this is my 5 pregnancy after 4 miscarriages. I was officially 7 weeks yesterday and had my first scan and everything was perfect.
