faint pink blood

Around 2 am  I woke up to go to the washroom and as I wiped I noticed some very faint pink on the toliet paper. Therefore I wiped again and there was still very faint pink blood. I called my doctor this morning and they didn't seem concerned at all but I'm such a worry wart. Have any of you other experience this, is that normal? They said if there was any cramps, pelvic pain, and or vaginal discharge of any sort then I should  worry and go straight to the ER. I'm still very panicked about this since they tell me I'm high-risk miscarriage. This morning the blood was a bit darker 😞
