Weird TMI symptom!!!

Cheyenne • I an 27 and I have a 3 year old boy, 6 year old boy, a 7 year old little girl, and 16 month old little girl
Okay I am 14.4 weeks with my first and in the last few days I have had a strange new symptom. It kinda feels like my vagina (sorry tmi) is stretching. I'm not having cramps or contractions that I know of so I don't think it's early labor. It doesn't really hurt just feels weird. Had anyone experienced this?
