Miserable

Kat • I am a Texan abroad with my sweet hubby and a beautiful 19 month old daughter and trying to conceive our second child.
I am 33+4 and strained my back this weekend causing kiddo to hop way up into my ribs. My whole belly looks different, my back is super sore, and I am having horrible heartburn after eating with the baby up so high. Has this happened to anyone else?
