I'm not sure I guess is more like achy pains or cramps not to bad ..
What kind of pain is it? Sharp pain? Achy pains? Cramps? If it is achy pain but tolerable your probably just feeling a lot of stretching. If it's sharp pain it could be round ligament pain (totally normal) but if it's really bad like your being stabbed then go to your hospital cause that wouldn't be normal. If it's cramping that comes and goes it could be contractions so go to the hospital to rule out preterm labor. With any of the above, you should stay off of your feet n drink TONS of water to get hydrated.
