I need help! im confused.

so with my period being regular I usually dont even bother looking at a calender. see ya next month. 26~29 days. well april I did d deed with my man around time was due and after I started. it would stop ten minutes later. this happened 4 times. finally it stayed for a day or two by its self and then stopped. well. basically april 12~may 25 we was rabbits. like every day. but in beginning of may I started getting moody and crazy and mean and craving hot sauce wich I hated but I drank from the bottle at three in the mornin. ice cream. french frys. I had to have it. and I was like screaming and wanting to punch him for not getting me everything I wanted.... pregnancy symptoms were there boobs hurt nausua fatigue, and that was like two weeks before my late period. confusing part: ten days late. pink discharge on 28th. grew heavier and was red but I was barely filling up 3 panty liners the first two days. and the 30th it was two and this morning. brown discharge and its leaving. its so much lighter. no cramps no period signs no clots just light bleeding. my lower back hurts a mild bit... my boobs have been hurting since earlier in may and I do feel a pain in side when I bend over to fast. my stomach feels full. but I think its trapped gas bc when stretching pain in side goes away. belly gurgles and bloats and pain is over. I just have no idea what this bleeding is? abnormal period? I took an equate in early may it said no... so any clues??
