Is having sore muscles & full body aches normal during pregnancy? I'm almost 15 weeks & I cried today when my puppy hit my calf muscle because it hurt so bad. My legs, shoulders, forearms, neck, thighs, & lower back are in so much pain that it hurts to move. I'm pretty sure I don't have the flu because the only other symptom I have is sneezing, & that's just because my allergies have gotten terrible during pregnancy. Anyone else just EXTREMELY sore around 15 weeks? I have a history of potassium deficiency (& I'm allergic to every significant source of potassium) so I'm thinking it might be time to get the doc to check my potassium again & see if I need to get a few days of potassium pills, I just thought I'd check here first since I can't even call til next week.
