When are you due for your period? If it dosen't show when it is supposed to, take a HPT. You might be pregnant, you might not, you didn't give a lot of information to base off of.

is the not eating thing normal for you?
I went off food for the first 3 mths with my first and felt sick constantly with throwing up around the 10th and 11th week coz at 12wks i found out i was pregnant.
Do a test.

im 3days late my period was suppost to come on the 6 of june my breast are sore when i touch them i have back pain and lots of heartburn

I would take a test if I were you.

I DNT THROW UP I JUST FEEL SICK AND I HAVE ALOT OF HEARTBURNS
