ok, i was having trouble losing those last stubborn pounds that i had put on when i went on the pill, so i went off and they went away, thank god! but, now it has been almost 4 months and i haven't gotten a period. i went to the doctor yesterday and she said to give it 3 more months but she doesn't think i will get one because my body fat % is so low. she also said that all forms of the pill and the shots and everthing would cause me to gain the weight back because of the progesterones and estrogen in all of them. she said to be healthy and to know my estrogen levels are ok, i need to have at least 3 periods in a year. what do you ladies do about menstrating when you get to such a low body fat? i don't want to gain that weight back and have to go back on. any advice????
