Cramping and discharge

Hi,

I wasn’t really sure where to go with this as not many people know I’m pregnant. So here I am to see if anyone has had similar symptoms and had a viable pregnancy. I am 6 weeks 5 days according to the app with baby number 2. This morning I had some cramping and mild back pain, I then felt like I got my period so I went to the bathroom. There was a moderate amount of clear and slightly pink tinged discharge. I spoke with the on call who states this can just be normal early pregnancy symptoms ( as I know), and not to get too concerned unless I experience a large amount of bleeding. Anyone else experienced this? My first OB appt isn’t until the 25th, but I will be calling to follow up tomorrow.
