I can be soooo tired/exhausted

But as sooooon as night time comes or "bed time" comes I can NEVER fall asleep !!!!! It is so frustrating, it makes me want to cry !!' I feel soooo emotional the last couple of days !!! My boobs have been super sore &&& hurt so bad to the point where my Bf needs to suck on them that's how bad they hurt !!!! I've been constipated . My backs been killing me !!! Can't ever fall asleep . I've had very very light pink spotting .... Not even enough to fill a tampon . I just don't get what's going on !!!! & every once in a while I feel so sick !!!!! Ive had no cramps what so ever .
