My daughter has recently been passing small blood clots, even though she isn't on her menstrual. she is on the pill and mobic (meloxicam). any ideas?

See below: Break-through bleeding is not uncommon on birth control pills, especially if she is new to them. See prescribing doc to make sure her pill has correct balance of estrogen & Progesterone for her. Make sure she takes them same time every day & doesn't miss any days. Weight gain/loss, stress, change in physical activity can also affect menses.
