What is this weird feeling?

Bree • I`m 27 yrs old and have one son (8). I just had our second. Not sure if we're done or not.
For the last couple of days. (Right after my doctors appt.) I keep getting this weird feeling. It feels like the baby is literally balling up and taking something with her or a squeezing feeling. It's the best I can describe it. It doesn't hurt real bad just SUPER uncomfortable. It is also on my upper right hand side. Any ideas if it's baby for sure or my uterus?
