15 Weeks - Had a little spotting last night. Help?

Taylor • Slay your own dragons, Princess. ❤️
I'm absolutely thrilled to be 15 weeks and 1 day (to be exact), but last night as I went to use the restroom before bed I noticed a few smudges of pinkish blood on my toilet paper. It wasn't a lot and I never saw it after. I am waiting on a call back from my doctor but wanted to know if anyone else has had anything like this before? I didn't have and cramping and like I said, haven't seen it since. Just thought it was weird because I haven't had spotting since very early in my pregnancy. Appreciate any feedback!
