Belly dropped?Need xtra eyes!High risk & a bit nervous

Can you "drop" at 33 weeks? I can't tell, except for I'm having more pressure down there. Looking at my 30 week (red undies and top) compared to todays 33 week picture, I kind of see a subtle difference...??..

I need more eyes to give me their opinion (I'm high risk, and have only had preemies) on weekly progesterone injections for preterm labor and delivery. At our 30 week Ultrasound the technician said Hes in the correct position w/ his head down, but "very low. I was dilated to 1cm at the time. that was 3 weeks ago. Wondering if his "head" has "dropped" any farther lol.
