Am I going to have a baby

I had my period about 3 weeks ago but lately my husband has informed me that he has noticed changes in my mood, eatting habbits, and sleep schedule. He also told me that I have a small bumb. Im hoping im not but I wanted to see what everyone went through for their first time symptoms becase every ones bpdy is different. Im taking a test in the morning so update coming soon. (also we live with my father in law and my sibling in laws so if i am expecting how do i hide it for them i know i cant tell anyone till fist trimester is done but wouldnt the older sibling in laws and the father in law know?)
