So my ob sent me for bloodwork last week to confirm where she saw one Tiny dot on ultrasound a day after getting Faint lines on 4 tests and wants me to have more this wensday to make sure my levels are rising.. shes said im Very early.. Anyone else find out at like 3-4 weeks ? ii have twin girls that are Almost 2.. and im thinkin she just want to keep an eye on my levels bc of the multiple factor.. im very anxious bc ive been cramping with no blood.. advice ?
