watery bleeding.. anyone else?

Elle
I know lots of women do.. my midwife says not to worry as it's not accompanied by any serious pain or cramps. but today I've had faint red/pink watery stains almost every time I've wiped... anyone else have something similar? I'm 10weeks 3 days and we are going for first ultrasound tomorrow. is this around the time the placenta is taking over for the yolk sac, does anyone know? the internet was pretty vague on that question. thanks in advance ladies ✨
