Spotting 2 days after transvaginal US?

Kristy

I’m currently 6 weeks and I had my first ultrasound on Friday. Was able to see teeny tiny baby and heartbeat. Today I’m experiencing mild cramping and spotting. Could this be delayed spotting from the US or the beginning of something bad? I’m so nervous and such a mess! Waiting to hear from my doctor and praying for my teeny baby 💙
