Bloating that never quite goes away. Feeling stuffed after three bites of dinner. A dull ache in your pelvis that shows up nowhere near your cycle. On their own, each one is easy to blame on stress, diet, or a long week. Most women do exactly that.

You know your body better than any chart does. If something feels wrong, keep asking until someone listens.
