Could I be prego????

Hi girls, I have had four miscarriages in the past two years.  So here it is,  I started what I thought was my ms in the 5th it was not as heavy as it always was, very very little clots a little cramping but not as bad as they usually are, the second day I was just spotting, the 3 day nothing just a little pink every time I wiped fourth day a little blood dark blood.. Just for an hour or so maybe, then 5th day a very little pink then nothing at all. My boobs feel a little stiff I wanna say. I have a headache everyday sick to my tummy was takin a shower then just bam had to puke not hungry feeling at all just just has some toast and scrambled eggs with hot sauce an I'm not a spicy kind of person, my lower stomach feels like pressure , feels like I have to poop but can't .. Sorry for the novel but I don't wanna lose hope, been trying for so long.. Im a afraid to pee on that stick and see a big fat 0... Any help or insight would be great!!!!!!! Thank you
