Very very light spotting...

I’m 6w today and had some super light spotting last night (basically just some brown blood tinged CM), then nothing this morning, and now again just the slightest amount of blood again, even less than last night. I know this is potentially completely normal, but this is exactly the same week that I started spotting with my miscarriage in October, and it started very light and escalated.

Would it be really silly of me to call my midwife for this light of spotting just to see if there was any way they would bring me in early for an ultrasound? I’m not scheduled for one for another 3 weeks, and I know the general rule is to wait until it’s heavy/red bleeding, but I’m so terrified after last time.
