Ok so recently, about 3 weeks ago I was sick with a gastroenteritis I think this is the correct way to say it for a week I was sick mostly white foam and bile. On the second week I was well for few days but allways morning sick, and now on the third week since yesterday I been on going to the bathroom to vomit again all night all day, it makes it hard to eat, also my period is late nearly a month, could I be pregnant and that s what it s making me sick?
