Did the doctor do a blood test to check your HCG levels? What is it you mean by 'one on the half side'?
no he didn't and it was a half yes and half no so kinda of an error
Yes ask your doc to give you a blood test to check your hcg levels. That will tell you even if you're very early.
I don't understand how it can be a half yes, half no? Do you mean it it was a very faint positive? I still say, go back to your doc and ask for a blood test, that will determine for sure whether you are pregnant or not. If not maybe they can find some other reason as to why you haven't had you period.
