Hi all I'm new here I have question if someone could maybe help.

So a few days ago I had some bleeding brownish and pinkish it was not heavy at all. By the time I found out it left I only had it a day. Well I think so. I don't really have symptoms of pregnancy except for very bad back pain I had such bad back pain 2 days ago. And I have severe heartburn. And also today I ate about 10am and by 3pm I was starving, hands shaking, lightheaded starving. And I don't usually get hungry during the day.
