I always put it down to how crappy the antibiotics make me feel lol when I am on them I feel sick and have even less of an appetite than normal. I always find it funny that I never feel ill with the frequent infections until they start me on yet more antibiotics. My first weigh in at slimming world I was on antibiotics for a UTI lost 1.5lb, 2nd and 3rd weeks lost 3.5lb and 4.5lb, 4th week was on antibiotics for another UTI and gained 0.5lb (funny really since all my jeans are falling down) I didn't really do anything much different each week. I am sure that there will be plenty more before the baby is born so will have to see if I gain/lose less those weeks. ((hugs)) hope you feel better soon. Hugs Crystal xx
