My periods are getting irregular. Last period was in Oct. For the past two weeks my weight has been going up. Now I'm 6 lb heavier! I can gain up to 5 lb in a day. I'm not eating excessively so guessing it's water weight as my belly feels bigger and my breasts feel tender. I keep on waiting for my period to arrive so this weight gain can disappear. Anyone the same with weight gain/water retention?
