Im a 22 yr old healthy female but lately ive been feeling exhausted, bloated,constipated, moody and my breast seem heavy, my last period was on the 9th march but only lasted 3/4 days not like my regular 6 days and not as heavy either, is there a chance that these are early pregnancy signs and that i conceived before my last unusual period? I have not taken a HPT yet as im waiting to see if i get my period on the 9th April but would like to know what you think?
