I always gain a bit during ovulation and about 3-5 days before my period starts. this time I have dieted well - increased my activity and still put on weight for the last 4 days (I am due on on Friday) I have lost inches round my neck, hips, calf, thighs, upper and lower arms but put 1" on round my bust and 3.5" round my abdomen area.... so I know it is fluid and expect to see a big drop Sunday - Monday.
Does anyone else have such extreme fluctuations of weight through their cycle?
