So I just took a test yesterday and it was really positive and then this morning again it was positive. I am literally shaking with anxiety I'm so hungry but can't eat I barely even want to drink water I'm so nervous 😢 excited but nervous I'm only 21 and money is so tight with me and my boyfriend. I think I'm about 4 weeks and 3 days. Can I get an ultrasound this early when I go for a test?
