But I don't gain it back?
any abnormality in periods??pain??or something?might be due to increase physical activity or some kind of exercise
If you're really losing and not gaining back you must be so thin. It's normal for the body to increase a few pounds before a lot of times because we crave salt which retains water in the body. During a period many bloat adding weight then when it's done that water weight, blood and bloat go down. I fluctuate 5 lbs or so. I have an irregular period so seeing a few pounds go on is sometimes a clue for me that I'm going to start soon. If you're truly losing fat or muscle mass and losing 5-10 with each period you must be really thin and I'd see a doctor since you can keep losing like that.
Yes I am very thin. Around 83 pounds and 5"4'. I am concerned about the loss. But thanks. I will go see my docter. XX
