I'm 16 weeks and 3 days today. Obviously I know that being pregnant, especially in second trimester can cause tenderness but it's usually not as strong (it's not painful or rhythmic or anything aside from maybe a slight pinch) and it feels like it came on completely randomly. I know it's a sign of growing but it just feels like it's growing really fast if that makes sense? Like it's getting bigger RIGHT NOW. Idk maybe I'm crazy it's just really uncomfortable and I want reassurance lol. Anyone experienced this?
