So I am not quite sure how to feel. My period is usually runs off a 22-25 day cycle and I was 5 days late with morning sickness and frequent unrinations and I always feel like I'm on the brink of passing out I just stay tired I have taken multiple pregnancy test a couple of them have showed faint lines but it was after the allotted time... I went to the clinic and they told me I have to go based off a 28 day cycle and based off that I was 2 days late. I started my period but it isnt normal its bright red and slimmy then watery like its barely there. My flow is usually heavy for 4days then light the last day I started my period on Sat and it was a lighter flow then normal and same things on Sunday and Monday its basically gone and now I'm back to my throwing up but I'm on my period!!! I'm confused as hell and my period ended today so it was only 3days and light and on top of that it was 2 days shorter than normal idk what to think my fiancé keeps tellin me he has baby fever and he thinks I am
