Your body is expanding lol. I'll be 18 weeks on Tuesday and feel the same. My doctor warned me about the cramping back aches chest aches head aches and even some sharp pain in the from from everything shifting and growing.
No nothing like that. My body must feels like it's aching all over. It's hard to explain.
Are you having another other symptoms? Painful urination, or urgency? back pain? Is your temperature elevated?
