I have heavy, sore and tingly brests with very sensitive nipples (which are not normally so), cramping in my lower abdomen, an almost complete loss of appetite (i was forced to eat and just kept it down), my cervix (which is usually hard and round no matter my cycle) has gone all soft and spongy, I had weird brown spotting for a day and rarely get af but when i do it is always heavy, i have a pile that has become very aggitated in the last two days, my sleeping pattern is completely screwed and i cant really sleep, when i do get sleep i still feel exhausted, I have gotten a huge acne breakout and got my first nose bleed in over a year.

Could this be pregnancy?
What else could it be?
