Heavy breasts and abdomen, nauseus, more pregnant symptoms, neg hpt, late period? what's wrong?

Hormonal symptoms: "pregnancy" symptoms are from pregnancy hormones but these symptoms can occur if hormone levels are different from usual. Bloating often occurs with high estrogen levels which can occur from ovarian cysts. This can also delay a menses. If an ovary makes extra estrogen and progesterone, then tender breasts or nausea and a delayed menses may occur.

See a doctor: You could have a variety of hormonal problems, including high prolactin, or a mass in the abdomen could also cause these symptoms. You need to be examined.
