Oh I get those too,,,,and I also get BH with very painful lower back pain at the same time too,,,really knocks the wind out of me when i get them.
As for the pressre down below,,,,,OMG,, I have never had it so bad. But when I get it badly, if I rub my lower abdomen just above my pelvic bone,,, I can feel bubs head bulging over the edge,,,so I am not sure if bubs is trying to work himself lower and cant,,or if he is just is some really bad position??
But as the other have said,,,not long now, and this will all be just a memory
