Third Pregnancy feels... different

I know each and every pregnancy is different for each of us but this time everything is so different;

I had no cramping with either previous pregnancies but this time around it’s a lot. I’m a pretty active woman, I work in long term care so I’m always on the move at work. Plus a 2 hour walk after work with my family and on weekends I don’t work. I’m feeling dull, muscle pulling like cramping while working or walking. Today was my day off and I took it easy until about 3pm when I started laundry. And now I’ve got that period cramp feeling. Never any spotting or out of the norm discharge with the cramping though.

I’m not overly worried that it’s bad bad, but I’m sure gonna call my Dr in the morning. I’m just scared I’ll have to go off work early. I would not do well on bed rest.
