Hello, As per the <a href="https://play.google.com/store/apps/details?id=com.glow.android.nurture">due date calculator</a>, I'm 7 weeks pregnant. Went to have ultrasound today. Doctor confirmed the pregnancy thro urine test. But said she cant see anything inside the sac though its been 7 weeks. Very much worried. Waiting for hormone test results. Anyone faced dis pblm??
