So I'm 8 days late on my period and I've been taking hp tests for the last week but there all coming back negitive :(. I've also been having some tenderness to my boobs and I've been throwing up the last few days! My food hasn't really changed much just haven't really been able to eat because of being sick! Have a little bit of cramping but nothing like getting my period. Does anyone have any advise I could really use some!
