Recently, on Monday, I took a blood test that says positive. Today I had an appointment for pap and the Dr did an ultrasound but he told me that he can't see anything. He told me that it can be an too early to see it or maybe ectopic pregnancy. I was reading around and some people say something about the sack (here's when you can notice this is my first time pregnant) but my Dr didn't say anything about it. Told me that make a quantitative test. By experience, Any of you can told me anything about this situation?
