I'm having period like pain, that dull-achy feeling you get when you are on your period or pmsing. I get it pretty much every day for a lot of the day on and off. I never had this with my first pregnancy... do you guys feel this also? Or know what it is? I'm assuming it's just growing pains, but I'm not sure. It's not a sharp pain or a pain that feels like stretching. The only way I can describe it is period pain...
