Blood test results🙁
So i went for a blood test Tuesday got the result today it was in 260 they sent me back for another today and told me it should be doubled so in the 500's.  She just called me and said it's only in the 300's.    
She said it could be it could be a ectopic pregnancy Or it could be fine and just slowly rising 😕
 Just last month kinda they same thing happen.    My period was suppose to start yesterday and it hasn't yet. 
Has anyone had this happen and they were fine and still had a baby?!
