x-posted spotting

I got a Doppler the other day and I decided to use it last night and again this morning. I wasn’t really picking anything up because I’m only 9w5d but I really wanted to hear baby so I was pressing down really hard. Like my abdomen is sore now. I went to the bathroom after I used the Doppler and there was a bit of very dark red blood on the toilet paper. I freaked and started balling my eyes out. I’m not having any cramping, I just have a sore tummy from pressing so hard. An hour or so later I went to the bathroom again and it was only pink mixed with some CM. It’s been a few hours now and there’s the slightest bit of pink when I wipe but it’s barely noticeable. I’m scared. I miscarried in January with my first. I’m so scared of losing another. Has this happened to anyone?
