Carrying so low

Madison

I’m 18w4d with baby #3. It’s our first boy! I’m also 33 so a bit older than my early 20’s pregnancies lol but this child is so low, he’s below my pants line and I’m 5’8”. Nothing is comfortable and my belly isn’t big enough for over the belly maternity. Is it common for 3rd pregnancy to sit so low? Will he move up? Makes me nervous for him getting bigger and sitting so low! Ouch!
