I had what I thought was my period 11 days ago, however it was only for one day and I had brown discharge for the next couple of days after. Since then I have been constipated, exhausted, constantly hungry but feel sick when it comes to eating as I feel so full. I have a strong sense of smell, when my fiancée opens a can of larger in the kitchen I can smell it a mile off. I’ve taken a pregnancy test today and it came back negative. I have no clue what is going on with my body, but all of my symptoms lead to pregnancy.
