9 weeks and spotting

i know many people comment that spotting can be normal as long as it isn’t red blood... i’m just worried anyway. no cramps or anything and i haven’t spotted until today at almost 9 weeks. my first ultrasound is on thursday. should i wait? not motivated to go to the er for spotting but a little nervous because of possibility of miscarriage at this stage. i’ve been having sex regularly and have not spotted before but what i did differently today was used my vibrator for the first time since pregnancy. i wasn’t rough with it and didn’t go super deep so i wouldn’t have guessed that i hit my cervix... *please be healthy, baby*
