Ok, so I went to the dr this morning and she did an exam and said that my cervix was closed and she didn't see any blood coming out of my cervix, which she said is good. They did a urine pregnancy test and it came back negative. But the blood work says that I am very sure pregnant. I was still bleeding a little this morning, but she said that I should stop. They did blood work and are going to compare the numbers with the blood work done on Monday. Should I be worried?

Without knowing your complete and total history it is hard to say if you should be worried.

Some women do bleed in early pregnancy and I am sure that this is what the doctor is looking at.

How far along are you?

I bled after my first pelvic exam with my first pregnancy. Call your OB if you are worried.

Well, the first dr I went to said that I was about 3-4 weeks, but the dr I went to this morning said that I was only about 2 weeks. I don't have any medical problems. I'm just wondering this early on if it could be my period.

It is odd that they have different opinions of your state of pregnancy. My OB carried around a wheel device that determined my due date by the time of my last period.

Well, that is what the first doctor went by, but according to the hormone levels (or what it is that tells them you are pregnant) it says that I am only about 1-2 weeks

You are in that horrible "just wait and call us if it gets worse" phase. I wish you the best.
