Please help!?!? Reduced baby movements?

I am nearly 33 wks pregnant.
I was @ the hospital on Monday with pains in my lower back, tummy and hips…they think I havent got over an infection as I have risen white blood cells and protein in my urine.

Baby was monitored on monday, all was well….very active as normal.

Today since lunch – babys movements seem to have gone more or less silent. When I eat, I usually get lots of kicks – hardly anything. At night, baby kicks me when I lie on my side – nothing.

I am getting some movements, lower in my abdomen but feel more like butterflies, you would miss them if you didnt concentrate.

I have got up out of bed, worried. Dont know what to do?????

I dont want to seem like im always at the hospital if u know what I mean……Plus my hubby has work tomorrow….
I have had a bath today, it usually kicks like mad – I think I had about 3 kicks in the whole hour I was in there.
