Swelling

So I'm 36+2 and within the past 3 days my entire body has swollen up immensely. First my feet, now my limbs, hands and face. I don't think it's preeclampsia because I just had my urine tested last week and it was clean. I guess my question is, is this normal? I did catch a really bad cold the night before xmas eve, sweat out 5 fevers total. Could this contribute to the fluid retention? I already drink a gallon a day idk what else to do I'm super duper uncomfortable ;(
