I'm really starting to worry. I've always had very light, short periods on Loestrin
24Fe, but I usually don't MISS periods
. I don't have any other symptoms other than the missed period. The only thing I can think of is that I do weightlift, but not "strenuously" (only heavy lifting a few times a week) and I'm not even lifting that heavy (just squatting 100 lb). I'm 5'6", 120 lb and 20% body fat, so nothing outrageous there.
