Ive had noticeble mood changes, headaches for a week, night sweats and hot flashes for 4 days. When i stretch i feel cramps in my lower abdomen. Dreaming every night for a week, one nipple is sore, both seem slightly darkend? nauseated briefly 5 times, ive napped 3 times this last week, fatigued and tired, no motivation. Ive taken 4 pregnancy tests all negative. is it still too early
