TMI!!! With pic!

Kennedy • Married to my soulmate since 7.4.2020!💍💞 We have a 4 year old son, who took a year and a half to conceive! We are expecting baby girl March 11th 2021 after 2 1/2 years of ttc with fertility treatments 💖
Im not sure what this is. I wiped and I got this string of blood on my toilet paper. Never had this before. I dont think its implantation bleeding.. But it could be. I got off my period about 2 weeks ago and Im not due for another 2 weeks. Any ideas?!
