21 weeks with baby boy

So this is my second lil baby boy and I am carrying this one sooooo much different than the first. Does anyone else have such a low baby that your already waddling and already hurting? Went to doc apt yesterday and she had to bring the heart monitor clear down to like my pelvic bone to even find his heart beat (and placenta is in between my belly and baby which makes it harder)! Hopefully this makes for an easy delivery 😳
