So im 36 weeks and we went to a theme park. I didnt ride any rides just swam and ALOT pf walking. Like 8+ hours. By the end of the night i was in so much pain. Cramping sides aching back. I figured thats what u get for walking all damn day. But when i got to the hotel i noticed my pee was a pinkish color....im kinda freaking out!! Any advice?! Its only when i pee. We're 3 hrs from home with bfs family idk what to think or do.
